Hans Petter Selasky 98a998d5e7 Update the mlx5 shared driver code to the latest version, which 
include the following list of changes:

- Added eswitch ACL table management
  Introduce API for managing ACL table.
  This API include the following features:
  1) vlan filter - for VST/VGT+ support.
  2) spoofcheck.
  3) robust functionality to allow/drop general untagged/tagged traffic.
  4) support for both ingress and egress ACL types.

- Added loopback filter to the vacl table.

- Added multicast list set in the vPort context

- Added promiscuous mode set in the vPort context

- Set the vlan list in vPort context
  1) Check caps if VLAN list is not longer than FW supports
  2) Set MODIFY_NIC_VPORT_CONTEXT command

- Changed MLX5_EEPROM_MAX_BYTES from 48 to 32 so that a single EEPROM
  reading cannot cross the 128-byte boundary. Previously reading the
  MCIA register was done in batches of 48 bytes. The third reading
  would then by-pass the 127th byte, which means that part of the low
  page and part of the high page would be read at the same time, which
  created a bug:
    1st: 0-47 bytes
    2nd: 48-95 bytes
    3rd: 96-143 bytes
