[PATCH v2] net/mlx5/hws: fix fragmented ptype match

[Alexander Kozyrev]

Fragmented PTYPE matching requires setting the mask to the exact
RTE_PTYPE_L4_FRAG value to avoid conflicts with other L4 types.
Adding L2 or L3 types to the same mask should be allowed,
but there is a check for the exact value for setting the definer.
This prevents the fragmented packets from matching in case of L2/L3
mask is provided as well. Mask out L2/L3 types when setting L4_FRAG.

Fixes: 761439a20f net/mlx5/hws: support fragmented packet type matching
