-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Change the type of the middle struct member currently causing
trouble from `struct tc_u32_sel` to `struct tc_u32_sel_hdr`.
Fix the following warning:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_tc_u32_parse.h:245:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

Although it seems unlikely in practice - there would need to be
rx ring indexes greater than 10^10 - it is theoretically possible
for the filename of per rx ring debugfs files to be truncated.
This is because although a 16 byte buffer is provided, the length
of the filename is restricted to 10 bytes. Remove this restriction
and allow the entire buffer to be used.
Also reduce the buffer to 12 bytes, which is sufficient.
Given that the range of rx ring indexes likely much smaller than the
maximum range of a 32-bit signed integer, a smaller buffer could be
used, with some further changes. But this change seems simple, robust,
and has minimal stack overhead.

This corrects an out-by-one error in the maximum length of the package
version string. The size argument of snprintf includes space for the
trailing '\0' byte, so there is no need to allow extra space for it by
reducing the value of the size argument by 1.
Found by inspection.

Macro `SIMPLE_DEV_PM_OPS()` is deprecated.
This patch replaces `SIMPLE_DEV_PM_OPS()` with

They are __init, so they are freed after init is done. But this
obfuscates the code.
Provided these days, we usually don't print anything if everything has
gone fine, drop the info print completely (along with now unused and
always artificial SIXPACK_VERSION).
And move the other string into the printk proper (while converting from
KERN_ERR to pr_err()).

'struct config_item_type' is not modified in this driver.
This structure is only used with config_group_init_type_name() which takes
a const struct config_item_type* as a 3rd argument.
This also makes things consistent with 'netconsole_target_type' witch is
already const.
Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

Add support for offloading cls U32 filters. Only "skbedit queue_mapping"
and "drop" actions are supported. Also, only "ip" and "802_3" tc
protocols are allowed. The PF must advertise the VIRTCHNL_VF_OFFLOAD_TC_U32
capability flag.
Since the filters will be enabled via the FD stage at the PF, a new type
of FDIR filters is added and the existing list and state machine are used.
The new filters can be used to configure flow directors based on raw
(binary) pattern in the rx packet.
Examples:
0. # tc qdisc add dev enp175s0v0 ingress
1. Redirect UDP from src IP 192.168.2.1 to queue 12:
# tc filter add dev <dev> protocol ip ingress u32 \
match u32 0x45000000 0xff000000 at 0 \
match u32 0x00110000 0x00ff0000 at 8 \
match u32 0xC0A80201 0xffffffff at 12 \
match u32 0x00000000 0x00000000 at 24 \
action skbedit queue_mapping 12 skip_sw
2. Drop all ICMP:
# tc filter add dev <dev> protocol ip ingress u32 \
match u32 0x45000000 0xff000000 at 0 \
match u32 0x00010000 0x00ff0000 at 8 \
match u32 0x00000000 0x00000000 at 24 \
action drop skip_sw
3. Redirect ICMP traffic from MAC 3c:fd:fe:a5:47:e0 to queue 7
(note proto: 802_3):
# tc filter add dev <dev> protocol 802_3 ingress u32 \
match u32 0x00003CFD 0x0000ffff at 4 \
match u32 0xFEA547E0 0xffffffff at 8 \
match u32 0x08004500 0xffffff00 at 12 \
match u32 0x00000001 0x000000ff at 20 \
match u32 0x0000 0x0000 at 40 \
action skbedit queue_mapping 7 skip_sw
Notes on matches:
1 - All intermediate fields that are needed to parse the correct PTYPE
must be provided (in e.g. 3: Ethernet Type 0x0800 in MAC, IP version
and IP length: 0x45 and protocol: 0x01 (ICMP)).
2 - The last match must provide an offset that guarantees all required
headers are accounted for, even if the last header is not matched.
For example, in #2, the last match is 4 bytes at offset 24 starting
from IP header, so the total is 14 (MAC) + 24 + 4 = 42, which is the
sum of MAC+IP+ICMP headers.

In preparation for a second type of FDIR filters that can be added by
tc-u32, move the add/del of the FDIR logic to be entirely contained in
iavf_fdir.c.
The iavf_find_fdir_fltr_by_loc() is renamed to iavf_find_fdir_fltr()
to be more agnostic to the filter ID parameter (for now @loc, which is
relevant only to current FDIR filters added via ethtool).
The FDIR filter deletion is moved from iavf_del_fdir_ethtool() in
ethtool.c to iavf_fdir_del_fltr(). While at it, fix a minor bug where
the "fltr" is accessed out of the fdir_fltr_lock spinlock protection.

A recent change to the driver exposed a bug where the MAC RX
filters (unicast MAC, broadcast MAC, and multicast MAC) are
configured and enabled before the RX path is fully initialized.
The result of this bug is that after the PHY is started packets
that match these MAC RX filters start to flow into the RX FIFO.
And then, after rx_init() is completed, these packets will go
into the driver RX ring as well. If enough packets are received
to fill the RX ring (default size is 128 packets) before the call
to request_irq() completes, the driver RX function becomes stuck.
This bug is intermittent but is most likely to be seen where the
oob_net0 interface is connected to a busy network with lots of
broadcast and multicast traffic.
All the MAC RX filters must be disabled until the RX path is ready,
i.e. all initialization is done and all the IRQs are installed.

doorbell rings
After napi_complete_done() is called when NAPI is polling in the current
process context, another NAPI may be scheduled and start running in
softirq on another CPU and may ring the doorbell before the current CPU
does. When combined with unnecessary rings when there is no need to arm
the CQ, it triggers error paths in the hardware.
This patch fixes this by calling napi_complete_done() after doorbell
rings. It limits the number of unnecessary rings when there is
no need to arm. MANA hardware specifies that there must be one doorbell
ring every 8 CQ wraparounds. This driver guarantees one doorbell ring as
soon as the number of consumed CQEs exceeds 4 CQ wraparounds. In practical
workloads, the 4 CQ wraparounds proves to be big enough that it rarely
exceeds this limit before all the napi weight is consumed.
To implement this, add a per-CQ counter cq->work_done_since_doorbell,
and make sure the CQ is armed as soon as passing 4 wraparounds of the CQ.

The code to lookup the scatter gather table entry assumed that it was
possible to use sg_virt() in order to lookup the DMA address in a mapped
scatter gather table. However, this assumption is incorrect as the DMA
mapping code may merge multiple entries into one. In that case, the DMA
address space may have e.g. two consecutive pages which is correctly
represented by the scatter gather list entry, however the virtual
addresses for these two pages may differ and the relationship cannot be
resolved anymore.
Avoid this problem entirely by working with the offset into the mapped
area instead of using virtual addresses. With that we only use the DMA
length and DMA address from the scatter gather list entries. The
underlying DMA/IOMMU code is therefore free to merge two entries into
one even if the virtual addresses space for the area is not continuous.

traversal
Current issue:
- The `target_list_lock` spinlock is held while iterating over
target_list() entries.
- Mid-loop, the lock is released to call __netpoll_cleanup(), then
reacquired.
- This practice compromises the protection provided by
`target_list_lock`.
Reason for current design:
1. __netpoll_cleanup() may sleep, incompatible with holding a spinlock.
2. target_list_lock must be a spinlock because write_msg() cannot sleep.
(See commit b5427c27173e ("[NET] netconsole: Support multiple logging
targets"))
Defer the cleanup of the netpoll structure to outside the
target_list_lock() protected area. Create another list
(target_cleanup_list) to hold the entries that need to be cleaned up,
and clean them using a mutex (target_cleanup_list_lock).

The new generation Loongson LS2K2000 SoC and LS7A2000 chipset are
equipped with the network controllers called Loongson GNET. It's the
single and multi DMA-channels Loongson GMAC but with a PHY attached.
Here is the summary of the DW GMAC features the controller has:
DW GMAC IP-core: v3.73a
Speeds: 10/100/1000Mbps
Duplex: Full (both versions), Half (LS2K2000 GNET only)
DMA-descriptors type: enhanced
L3/L4 filters availability: Y
VLAN hash table filter: Y
PHY-interface: GMII (PHY is integrated into the chips)
Remote Wake-up support: Y
Mac Management Counters (MMC): Y
Number of additional MAC addresses: 5
MAC Hash-based filter: Y
Hash Table Size: 256
AV feature: Y (LS2K2000 GNET only)
DMA channels: 8 (LS2K2000 GNET), 1 (LS7A2000 GNET)
Let's update the Loongson DWMAC driver to supporting the new Loongson
GNET controller. The change is mainly trivial: the driver shall be
bound to the PCIe device with DID 0x7a13, and the device-specific
setup() method shall be called for it. The only peculiarity concerns
the integrated PHY speed change procedure. The PHY has a weird problem
with switching from the low speeds to 1000Mbps mode. The speedup
procedure requires the PHY-link re-negotiation. So the suggested
change provide the device-specific fix_mac_speed() method to overcome
the problem.

The Loongson DWMAC driver currently supports the Loongson GMAC
devices (based on the DW GMAC v3.50a/v3.73a IP-core) installed to the
LS2K1000 SoC and LS7A1000 chipset. But recently a new generation
LS2K2000 SoC was released with the new version of the Loongson GMAC
synthesized in. The new controller is based on the DW GMAC v3.73a
IP-core with the AV-feature enabled, which implies the multi
DMA-channels support. The multi DMA-channels feature has the next
vendor-specific peculiarities:
1. Split up Tx and Rx DMA IRQ status/mask bits:
Name Tx Rx
DMA_INTR_ENA_NIE = 0x00040000 | 0x00020000;
DMA_INTR_ENA_AIE = 0x00010000 | 0x00008000;
DMA_STATUS_NIS = 0x00040000 | 0x00020000;
DMA_STATUS_AIS = 0x00010000 | 0x00008000;
DMA_STATUS_FBI = 0x00002000 | 0x00001000;
2. Custom Synopsys ID hardwired into the GMAC_VERSION.SNPSVER register
field. It's 0x10 while it should have been 0x37 in accordance with
the actual DW GMAC IP-core version.
3. There are eight DMA-channels available meanwhile the Synopsys DW
GMAC IP-core supports up to three DMA-channels.
4. It's possible to have each DMA-channel IRQ independently delivered.
The MSI IRQs must be utilized for that.
Thus in order to have the multi-channels Loongson GMAC controllers
supported let's modify the Loongson DWMAC driver in accordance with
all the peculiarities described above:
1. Create the multi-channels Loongson GMAC-specific
stmmac_dma_ops::dma_interrupt()
stmmac_dma_ops::init_chan()
callbacks due to the non-standard DMA IRQ CSR flags layout.
2. Create the Loongson DWMAC-specific platform setup() method
which gets to initialize the DMA-ops with the dwmac1000_dma_ops
instance and overrides the callbacks described in 1. The method also
overrides the custom Synopsys ID with the real one in order to have
the rest of the HW-specific callbacks correctly detected by the driver
core.
3. Make sure the platform setup() method enables the flow control and
duplex modes supported by the controller.

The Loongson GMAC driver currently supports the network controllers
installed on the LS2K1000 SoC and LS7A1000 chipset, for which the GMAC
devices are required to be defined in the platform device tree source.
But Loongson machines may have UEFI (implies ACPI) or PMON/UBOOT
(implies FDT) as the system bootloaders. In order to have both system
configurations support let's extend the driver functionality with the
case of having the Loongson GMAC probed on the PCI bus with no device
tree node defined for it. That requires to make the device DT-node
optional, to rely on the IRQ line detected by the PCI core and to
have the MDIO bus ID calculated using the PCIe Domain+BDF numbers.
In order to have the device probe() and remove() methods less
complicated let's move the DT- and ACPI-specific code to the
respective sub-functions.

Loongson delivers two types of the network devices: Loongson GMAC and
Loongson GNET in the framework of four SOC/Chipsets revisions:
Chip Network PCI Dev ID Synopys Version DMA-channel
LS2K1000 SOC GMAC 0x7a03 v3.50a/v3.73a 1
LS7A1000 Chipset GMAC 0x7a03 v3.50a/v3.73a 1
LS2K2000 SOC GMAC 0x7a03 v3.73a 8
LS2K2000 SOC GNET 0x7a13 v3.73a 8
LS7A2000 Chipset GNET 0x7a13 v3.73a 1
The driver currently supports the chips with the Loongson GMAC network
device synthesized with a single DMA-channel available. As a
preparation before adding the Loongson GNET support detach the
Loongson GMAC-specific platform data initializations to the
loongson_gmac_data() method and preserve the common settings in the
loongson_default_data().
While at it drop the return value statement from the
loongson_default_data() method as redundant.
Note there is no intermediate vendor-specific PCS in between the MAC
and PHY on Loongson GMAC and GNET. So the plat->mac_interface field
can be freely initialized with the PHY_INTERFACE_MODE_NA value.
