bnxt_en: Use absolute target ns from ptp_clock_request

2026-05-06T00:36:15+00:00

There is no need to calculate the target PHC cycles required
to make phase adjustment on the PPS OUT signal. This is because
the application supplies absolute n_sec value in the future and
is already the actual desired target value.

Remove the unnecessary code.

bnxt_en: Check return value of bnxt_hwrm_vnic_cfg

2026-05-06T00:36:14+00:00

When the bnxt RDMA driver is loaded, it calls bnxt_register_dev().
As part of this, driver sends HWRM_VNIC_CFG firmware command
to configure the VNIC to operate in dual VNIC mode. Currently
the driver ignores the result of this firmware command. The RDMA
driver must know the result since it affects its functioning.

Check return value of call to bnxt_hwrm_vnic_cfg() in
bnxt_register_dev() and return failure on error.

bnxt_en: Set bp->max_tpa according to what the FW supports

2026-05-06T00:36:14+00:00

Fix the logic to set bp->max_tpa no higher than what the FW supports.
On P5 chips, some older FW sets max_tpa very low so we override it to
prevent performance regressions with the older FW.

bnxt_en: Delay for 5 seconds after AER DPC for all chips

2026-05-06T00:36:14+00:00

The FW on all chips is requiring a 5-second delay after Downstream
Port Containment (DPC) AER.  The previously added 900 msec delay was
not long enough in all cases because the chip's CRS (Configuration
Request Retry Status) mechanism is not always reliable.

Merge tag 'net-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

2026-04-23T23:50:42+00:00

Pull  networking fixes from Jakub Kicinski:
 "Including fixes from Netfilter.

  Steady stream of fixes. Last two weeks feel comparable to the two
  weeks before the merge window. Lots of AI-aided bug discovery. A newer
  big source is Sashiko/Gemini (Roman Gushchin's system), which points
  out issues in existing code during patch review (maybe 25% of fixes
  here likely originating from Sashiko). Nice thing is these are often
  fixed by the respective maintainers, not drive-bys.

  Current release - new code bugs:

   - kconfig: MDIO_PIC64HPSC should depend on ARCH_MICROCHIP

  Previous releases - regressions:

   - add async ndo_set_rx_mode and switch drivers which we promised to
     be called under the per-netdev mutex to it

   - dsa: remove duplicate netdev_lock_ops() for conduit ethtool ops

   - hv_sock: report EOF instead of -EIO for FIN

   - vsock/virtio: fix MSG_PEEK calculation on bytes to copy

  Previous releases - always broken:

   - ipv6: fix possible UAF in icmpv6_rcv()

   - icmp: validate reply type before using icmp_pointers

   - af_unix: drop all SCM attributes for SOCKMAP

   - netfilter: fix a number of bugs in the osf (OS fingerprinting)

   - eth: intel: fix timestamp interrupt configuration for E825C

  Misc:

   - bunch of data-race annotations"

bnge: remove unsupported backing store type

2026-04-23T03:30:46+00:00

The backing store type, BNGE_CTX_MRAV, is not applicable in Thor Ultra
devices. Remove it from the backing store configuration, as the firmware
will not populate entities in this backing store type, due to which the
driver load fails.

bnxt: use snapshot in bnxt_cfg_rx_mode

2026-04-21T10:50:25+00:00

With the introduction of ndo_set_rx_mode_async (as discussed in [1])
we can call bnxt_cfg_rx_mode directly. Convert bnxt_cfg_rx_mode to
use uc/mc snapshots and move its call in bnxt_sp_task to the
section that resets BNXT_STATE_IN_SP_TASK. Switch to direct call in
bnxt_set_rx_mode.

bnxt: convert to ndo_set_rx_mode_async

2026-04-21T10:50:25+00:00

Convert bnxt from ndo_set_rx_mode to ndo_set_rx_mode_async.
bnxt_set_rx_mode, bnxt_mc_list_updated and bnxt_uc_list_updated
now take explicit uc/mc list parameters and iterate with
netdev_hw_addr_list_for_each instead of netdev_for_each_{uc,mc}_addr.

The bnxt_cfg_rx_mode internal caller passes the real lists under
netif_addr_lock_bh.

BNXT_RX_MASK_SP_EVENT is still used here, next patch converts to
the direct call.
