====================
mlx5-updates-2019-02-19

This series includes misc updates to mlx5 drivers and one ethtool update.

1) From Aya Levin:
   - ethtool: Define 50Gbps per lane link modes
   - add support for 50Gbps per lane link modes in mlx5 driver

2) From Tariq Toukan,
   - Add a helper function to unify mlx5 resource reloading

3) From Vlad Buslov,
   - Remove wrong and superfluous tc pedit header type check

4) From Tonghao Zhang,
   - Some refactoring in en_tc.c to simplify the mlx5e_tc_add_fdb_flow

5) From Leon Romanovsky & Saeed,
   - Compilation warning fixes

6) From Bodong wang,
   - E-Switch fixes that are related to the SmarNIC series
