====================
mlx5-updates-2021-10-25

Misc updates for mlx5 driver:

1) Misc updates and cleanups:
 - Don't write directly to netdev->dev_addr, From Jakub Kicinski
 - Remove unnecessary checks for slow path flag in tc module
 - Fix unused function warning of mlx5i_flow_type_mask
 - Bridge, support replacing existing FDB entry

2) Sub Functions, Reduction in memory usage:
 - Reduce flow counters bulk query buffer size
 - Implement max_macs devlink parameter
 - Add devlink vendor params to control Event Queue sizes
 - Added SF life cycle trace points by Parav/

3) From Aya, Firmware health buffer reporting improvements
 - Print health buffer by log level and more missing information
 - Periodic update of host time to firmware

 interface is not functional, which is the case in most FW fatal errors.
 The recover function runs recover flow which reloads the driver and triggers fw
 reset if needed.
+On firmware error, the health buffer is dumped into the dmesg. The log
+level is derived from the error's severity (given in health buffer).
