[dpdk-dev] [PATCH 2/3] net/ice: fix flow action validation

[Yang, Qiming]

Hi, Ying
For the action check reorganization, please according to Beilei's comments, use array  to stand the action element list.
And as we discussed before, it's better to change in the next release.

Subject: [PATCH 2/3] net/ice: fix flow action validation

Action is a list. We should check each element of the action rather than the first one.
This patch fixes this issue.

Fixes: d76116a4678f ("net/ice: add generic flow API")
