r8169: fix ASPM-related issues on a number of systems with NIC version from RTL8168h

2023-09-13T07:48:42+00:00

commit 90ca51e8c654699b672ba61aeaa418dfb3252e5e upstream. This effectively reverts 4b5f82f6aaef. On a number of systems ASPM L1 causes tx timeouts with RTL8168h, see referenced bug report.

igb: set max size RX buffer when store bad packet is enabled

2023-09-13T07:48:37+00:00

commit bb5ed01cd2428cd25b1c88a3a9cba87055eb289f upstream. Increase the RX buffer size to 3K when the SBP bit is on. The size of the RX buffer determines the number of pages allocated which may not be sufficient for receive frames larger than the set MTU size.

net/mlx5: Use RMW accessors for changing LNKCTL

2023-09-13T07:48:23+00:00

[ Upstream commit 30de872537bda526664d7a20b646adfb3e7ce6e6 ] Don't assume that only the driver would be accessing LNKCTL of the upstream bridge. ASPM policy changes can trigger write to LNKCTL outside of driver's control. Use RMW capability accessors which do proper locking to avoid losing concurrent updates to the register value.

pds_core: pass opcode to devcmd_wait

[ Upstream commit 0ea064e74bc8f915aba3f2d0fb3418247a09b73d ] Don't rely on the PCI memory for the devcmd opcode because we read a 0xff value if the PCI bus is broken, which can cause us to report a bogus dev_cmd opcode later.

cteonxt2-pf: Fix backpressure config for multiple PFC priorities to work simultaneously

2023-09-13T07:48:08+00:00

[ Upstream commit 597d0ec0e4ca6a912affea4cc94df08959e9ec74 ] MAC (CGX or RPM) asserts backpressure at TL3 or TL2 node of the egress hierarchical scheduler tree depending on link level config done. If there are multiple PFC priorities enabled at a time and for all such flows to backoff, each priority will have to assert backpressure at different TL3/TL2 scheduler nodes and these flows will need to submit egress pkts to these nodes. Current PFC configuration has an issue where in only one backpressure scheduler node is being allocated which is resulting in only one PFC priority to work. This patch fixes this issue.
