[dpdk-dev] [PATCH] net/mlx5: fix adjust priority for drop queue

[Nelio Laranjeiro]

Drop queue should also adjust their priority according the most specific
layer in the pattern they are matching to avoid dropping all the traffic.

Fixes: 8086cf08b2f0 ("net/mlx5: handle RSS hash configuration in RSS flow")
