[PATCH v7 00/10] selective Rx

[Thomas Monjalon]

This is a new feature in ethdev with tests and mlx5 implementation.
Selective Rx allows to receive partial data,
saving some hardware bandwidth.

Note 1: mlx5 support patch is not correctly indented
to make review easier. An indent patch follows to be squashed.

Note 2: DTS patch is an attempt to test the feature on day 1,
it is not mandatory if it is blocking the merge.

v2: rework after Gregory
v3: fix bugs found with AI by Stephen
v4: fix packet type in DTS test
v5: fix mlx5 Rx to handle discarding first segment
v6: fix reindent patch
v7: fix mlx5 CQE error handling + outdated mcqe + redundant assignment
