====================
mlx5-updates-2019-04-02

This series provides misc updates to mlx5 driver

1) Aya Levin (1): Handle event of power detection in the PCIE slot

2) Eli Britstein (6):
  Some TC VLAN related updates and fixes to the previous VLAN modify action
  support patchset.
  Offload TC e-switch rules with egress/ingress VLAN devices

3) Max Gurtovoy (1): Fix double mutex initialization in esiwtch.c

4) Tariq Toukan (3): Misc small updates
  A write memory barrier is sufficient in EQ ci update
  Obsolete param field holding a constant value
  Unify logic of MTU boundaries

5) Tonghao Zhang (4): Misc updates to en_tc.c
  Make the log friendly when decapsulation offload not supported
  Remove 'parse_attr' argument in parse_tc_fdb_actions()
  Deletes unnecessary setting of esw_attr->parse_attr
  Return -EOPNOTSUPP when attempting to offload an unsupported action
