Subject: net/ice: support mark only action for flow director
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0f664f7d57268f9ab9bdef95f0d48b3ce5004a61;p=dpdk.git

net/ice: support mark only action for flow director

This patch fixes issue that doesn't support mark only case.
Mark only action is equal to mark + passthru action.

Fixes: f5cafa961fae ("net/ice: add flow director create and destroy")
