[PATCH net 1/5] bnxt_en: Fix ethtool autoneg logic.

[Michael Chan]

1. Determine autoneg on|off setting from link_info->autoneg.  Using the
firmware returned setting can be misleading if autoneg is changed and
there hasn't been a phy update from the firmware.

2. If autoneg is disabled, link_info->autoneg should be set to 0 to
indicate both speed and flow control autoneg are disabled.

3. To enable autoneg flow control, speed autoneg must be enabled.

[PATCH net 2/5] bnxt_en: Cleanup and Fix flow control setup logic

[Michael Chan]

Cleanup bnxt_probe_phy() to cleanly separate 2 code blocks for autoneg
on and off.  Autoneg flow control is possible only if autoneg is enabled.

In bnxt_get_settings(), Pause and Asym_Pause are always supported.
Only the advertisement bits change depending on the ethtool -A setting
in auto mode.

[PATCH net 4/5] bnxt_en: Fix implementation of tx push operation.

[Michael Chan]

tx push is supported for small packets to reduce DMA latency.  The
following bugs are fixed in this patch:

1. Fix the definition of the push BD which is different from the DMA BD.
2. The push buffer has to be zero padded to the next 64-bit word boundary
or tx checksum won't be correct.
3. Increase the tx push packet threshold to 164 bytes (192 bytes with the BD)
so that small tunneled packets are within the threshold.

[PATCH net 5/5] bnxt_en: Reduce default ring sizes.

[Michael Chan]

The current default tx ring size of 512 causes an extra page to be
allocated for the tx ring with only 1 entry in it.  Reduce it to
511.  The default rx ring size is also reduced to 511 to use less
memory by default.

This series fixes a devlink bug and several XDP related bugs.  The
devlink bug causes a kernel crash on VF devices.  The XDP driver
patches fix and clean up the RX XDP path and re-enable header-data
split that was disabled by mistake when adding the XDP multi-buffer
support.

[PATCH net 0/5] bnxt_en: Bug fixes.

[Michael Chan]

[-- Attachment #1: Type: text/plain, Size: 1006 bytes --]

These 5 bug fixes are all related to the firmware reset or AER recovery.
2 patches fix the cleanup logic for the workqueue used to handle firmware
reset and recovery. 1 patch ensures that the chip will have the proper
BAR addresses latched after fatal AER recovery.  1 patch fixes the
open path to check for firmware reset abort error.  The last one
sends the fw reset command unconditionally to fix the AER reset logic.

Please queue these for -stable as well.  Thanks.

FWIW these will likely only reach 5.3 since it looks like the bug dates
to 5.1 but 5.1 and 5.2 branches of stable are already EOL.
