2026-01-21wifi: iwlwifi: mld: prevent EMLSR when NAN is activeMiri Korenblit
EMLSR is not allowed when NAN is active. Block EMLSR when starting NAN, and unblock EMLSR when NAN is stopped.

2026-01-21wifi: iwlwifi: mld: Fix primary link selection logicNidhish A N
When assigning emlsr.primary with emlsr.selected_primary we are checking if BIT(mld_vif->emlsr.selected_links) are a part of vif->active_links. This is incorrect as emlsr.selected_links is a bitmap of possibly two selected links. Therefore, performing the BIT() operation on it does not yield any meaningful result and almost always leads to incorrect primary link selection. Additionally, we cannot rely on vif->active_links at this stage of the link switch flow because it contains both the removed links and also the newly added links. For example, if we had selected links in the past (0x11) and we now select links because of TTLM/debugfs (0x100), vif->active_links will now be (0x111) and primary link will be 0, while 0 is not even an active link. Thus, we create our own bitmap of final active links.

2026-01-21wifi: iwlwifi: mld: fix chandef start calculationMiri Korenblit
A link pair in which both links are in 5 GHz can be used for EMLSR only if they are separated enough. To check this condition we calculate the start and the end of the chandefs of both links in the pair and do some checks. But the calculation of the start/end of the chandef is currently done by subtracting/adding half the bandwidth from/to the control channel's center frequency, when it should really be subtracted/added from/to the center frequency of the entire chandef. Fix the wrong calculation.

2026-01-21wifi: iwlwifi: mld: support TLC command version 6Miri Korenblit
In version 6, a phy id is added to the tlc command and the sta_id becomes a sta_mask. This change is required for NAN: - in NAN we can have 2 logical stations of the same physical station and with the same channel/band (2 NDIs with the same peer) - hence the sta_mask. - In NAN we can have more than one TLC configuration for a single station (for example if it operates on more than one channel) - so the FW needs to be able to find the right TLC context, based on the phy id. Populate the new version (for now with a single station id only. The other ones will be added later when NAN is implemented). In case the FW has a lower version than that - convert it to the FW version. Note that there is some code duplicantion in the conversions to v5 and to v4, but this is intentional since v5 will be removed as soon as v6 is supported.

Erroneously, the channel flags in the scan command for 6 GHz scan were mistakenly set using iwl_mld_scan_get_cmd_gen_flags, which actually calculates a different field (the general flags) in the command. However, these flags are not relevant for 6 GHz scan part, except for IWL_SCAN_CHANNEL_FLAG_6G_PSC_NO_FILTER, which is already set correctly. Since the incorrect flags are only applied in the 6 GHz scan part and are ignored by the firmware, this has no adverse effect.

2026-01-20usbnet: limit max_mtu based on device's hard_mtuLaurent Vivier
The usbnet driver initializes net->max_mtu to ETH_MAX_MTU before calling the device's bind() callback. When the bind() callback sets dev->hard_mtu based the device's actual capability (from CDC Ethernet's wMaxSegmentSize descriptor), max_mtu is never updated to reflect this hardware limitation). This allows userspace (DHCP or IPv6 RA) to configure MTU larger than the device can handle, leading to silent packet drops when the backend sends packet exceeding the device's buffer size. Fix this by limiting net->max_mtu to the device's hard_mtu after the bind callback returns.

2026-01-20net: txgbe: remove the redundant data return in SW-FW mailboxJiawen Wu
For these two firmware mailbox commands, in txgbe_test_hostif() and txgbe_set_phy_link_hostif(), there is no need to read data from the buffer. Under the current setting, OEM firmware will cause the driver to fail to probe. Because OEM firmware returns more link information, with a larger OEM structure txgbe_hic_ephy_getlink. However, the current driver does not support the OEM function. So just fix it in the way that does not involve reading the returned data.

2026-01-20net: stmmac: fix resume: calculate tso last_segmentRussell King (Oracle)
Tao Wang reports that sometimes, after resume, stmmac can watchdog: NETDEV WATCHDOG: CPU: x: transmit queue x timed out xx ms When this occurs, the DMA transmit descriptors contain: eth0: 221 [0x0000000876d10dd0]: 0x73660cbe 0x8 0x42 0xb04416a0 eth0: 222 [0x0000000876d10de0]: 0x77731d40 0x8 0x16a0 0x90000000 where descriptor 221 is the TSO header and 222 is the TSO payload. tdes3 for descriptor 221 (0xb04416a0) has both bit 29 (first descriptor) and bit 28 (last descriptor) set, which is incorrect. The following packet also has bit 28 set, but isn't marked as a first descriptor, and this causes the transmit DMA to stall. This occurs because stmmac_tso_allocator() populates the first descriptor, but does not set .last_segment correctly. There are two places where this matters: one is later in stmmac_tso_xmit() where we use it to update the TSO header descriptor. The other is in the ring/chain mode clean_desc3() which is a performance optimisation. Rather than using tx_q->tx_skbuff_dma[].last_segment to determine whether the first descriptor entry is the only segment, calculate the number of descriptor entries used. If there is only one descriptor, then the first is also the last, so mark it as such. Further work will be necessary to either eliminate .last_segment entirely or set it correctly. Code analysis also indicates that a similar issue exists with .is_jumbo. These will be the subject of a future patch.

2026-01-20octeontx2-pf: Remove unnecessary bounds checkSimon Horman
active_fec is a 2-bit unsigned field, and thus can only have the values 0-3. So checking that it is less than 4 is unnecessary. Simplify the code by dropping this check. As it no longer fits well where it is, move FEC_MAX_INDEX to towards the top of the file. And add the prefix OXT2. I believe this is more idiomatic. Flagged by Smatch as: ...//otx2_ethtool.c:1024 otx2_get_fecparam() warn: always true condition '(pfvf->linfo.fec < 4) => (0-3 < 4)' No functional change intended. Compile tested only.

2026-01-20eth: fbnic: Reuse RX mailbox pagesMohsin Bashir
Currently, the RX mailbox frees and reallocates a page for each received message. Since FW Rx messages are processed synchronously, and nothing hold these pages (unlike skbs which we hand over to the stack), reuse the pages and put them back on the Rx ring. Now that we ensure the ring is always fully populated we don't have to worry about filling it up after partial population during init, either. Update fbnic_mbx_process_rx_msgs() to recycle pages after message processing.
