Subject: [dpdk-dev] [PATCH] net/mlx5: fix validation of jump action
Date: Thu, 15 Aug 2019 12:26:51 +0300	[thread overview]
Message-ID: <aca9df2e188c0c205a241b51afa315a31247dae4.1565861014.git.dekelp@mellanox.com> (raw)

This patch updates the validation function of jump action.
It adds check of conflicting fate actions in flow rule.
It also removes check of action->type which is not needed.

Fixes: 684b9a1b1f5c ("net/mlx5: support jump action")
Cc: stable@dpdk.org
