Subject: net/mlx5: fix item validation in Direct Verbs
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6949c43c147c504087f367ee0c42939809a6473e;p=dpdk.git

net/mlx5: fix item validation in Direct Verbs

1) remove MPLS item in validation as it doesn't have a translator.

2) add missing NVGRE item to validation

3) match switch-case order between validation and translation.

Fixes: fc2c498ccb94 ("net/mlx5: add Direct Verbs translate items")
Fixes: 3d69434113d1 ("net/mlx5: add Direct Verbs validation function")
