====================
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
