Saeed Mahameed says:

====================
This patch series contains various fixes, additions and improvements to
mlx5 software steering.

Patch 1:
  adds support for REMOVE_HEADER packet reformat - a new reformat type
  that is supported starting with ConnectX-6 DX, and allows removing an
  arbitrary size packet segment at a selected position.

Patches 2 and 3:
  add support for VLAN pop on TX and VLAN push on RX flows.

Patch 4:
  enables retransmission mechanism for the SW Steering RC QP.

Patch 5:
  does some improvements to error flow in building STE array and adds
  a more informative printout of an invalid actions sequence.

Patch 6:
  improves error flow on SW Steering QP error.

Patch 7:
  reduces the log level of a message that is printed when a table is
  connected to a lower/same level destination table, as this case proves to
  be not as rare as it was in the past.

Patch 8:
  adds missing support for matching on IPv6 flow label for devices
  older than ConnectX-6 DX.

Patch 9:
  replaces uintN_t types with kernel-style types.

Patch 10:
  allows for using the right API for updating flow tables - if it is
  a FW-owned table, then FW API will be used.

Patch 11:
  adds support for 'ignore_flow_level' on multi-destination flow
  tables that are created by SW Steering.

Patch 12:
   optimizes FDB RX steering rule by skipping matching on source port,
   as the source port for all incoming packets equals to wire.

Patch 13:
   is a small code refactoring - it merges several DR_STE_SIZE enums
   into a single enum.

Patch 14:
   does some additional refactoring and removes HW-specific STE type
   from NIC domain.

Patch 15:
   removes rehash ctrl struct from dr_htbl struct and saves some memory.

Patch 16:
   does a more significant improvement in terms of memory consumption
   and was able to save about 1.6 Gb for 8M rules.

Patch 17:
   adds support for update FTE, which is needed for cases where there
   are multiple rules with the same match.
