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.

mptcp: Optimize received options handling

These patches optimize received MPTCP option handling in terms of both
storage and fewer conditionals to evaluate in common cases, and also add
a couple of cleanup patches.

Patches 1 and 5 do some cleanup in checksum option parsing and
clarification of lock handling.

Patches 2 and 3 rearrange struct mptcp_options_received to shrink it
slightly and consolidate frequently used fields in the same cache line.

Patch 4 optimizes incoming MPTCP option parsing to skip many extra
comparisons in the common case where only a DSS option is present.

Sub-opt specific flags are moved out of the suboptions area,

suboption is parsed.

This patch updates the function where the window clamp is set to also

To track each STE of the rule a rule member was allocated, each
member would point to one STE. This means that we would allocate
40B (rule member) * number of STEs per rule.

To reduce this per rule allocation we use the STE tree pointers
for next_htbl and pointing STE to navigate the tree, this allows
us to keep only the pointer to the last STE of rule (always unique).
From the last rule STE we are able to traverse and rebuild all of
the STEs that construct the rule.

In our testing with 8M rules, each consisting of 7 STES, we were able
to reduce 1.6GB of memory.
