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
