====================
mlx5-updates-2022-03-17

1) From Maxim Mikityanskiy,
   Datapath improvements in preparation for XDP multi buffer

   This series contains general improvements for the datapath that are
   useful for the upcoming XDP multi buffer support:

   a. Non-linear legacy RQ: validate MTU for robustness, build the linear
      part of SKB over the first hardware fragment (instead of copying the
      packet headers), adjust headroom calculations to allow enabling headroom
      in the non-linear mode (useful for XDP multi buffer).

   b. XDP: do the XDP program test before function call, optimize
      parameters of mlx5e_xdp_handle.

2) From Rongwei Liu, DR, reduce steering memory usage
   Currently, mlx5 driver uses mlx5_htbl/chunk/ste to organize
   steering logic. However there is a little memory waste.

   This update targets to reduce steering memory footprint by:
   a. Adjust struct member layout.
   b. Remove duplicated indicator by using simple functions call.

   With 500k TX rules(3 ste) plus 500k RX rules(6 stes), these patches
   can save around 17% memory.

3) Three cleanup commits at the end of this series.
