====================
mlx5-updates-2020-01-22

This series provides updates to mlx5 driver.
1) Misc small cleanups
2) Some SW steering updates including header copy support
3) Full ethtool statistics support for E-Switch uplink representor
Some refactoring was required to share the bare-metal NIC ethtool
stats with the Uplink representor. On Top of this Vlad converts the
ethtool stats support in E-Swtich vports representors to use the mlx5e
"stats groups" infrastructure and then applied all applicable stats
to the uplink representor netdev.
