> Subject: [PATCH] net/mlx5: fix wrong Flow Tag decompression
> Packets can get a wrong Flow Tag on x86 architecture with the Flow Tag
> compression format (rxq_cqe_comp_en=2) enabled inside the SSE Rx burst.
> The shuffle mask that extracts a Flow Tag from the pair of compressed CQEs is
> reversed. This leads to the wrong Flow Tag assignment.
> Correct the shuffle mask to get proper bytes for a Flow Tag from miniCQEs.
> Fixes: 54c2d46b160 ("net/mlx5: support flow tag and packet header
> miniCQEs")
