[dpdk-dev] [PATCH v4 25/26] net/mlx5: optimize Rx queue match

[Suanming Mou <suanmingm@nvidia.com>]

As hrxq struct has the indirect table pointer, while matching the
hrxq, better to use the hrxq indirect table instead of searching
from the list.

This commit optimizes the hrxq indirect table matching.
