[dpdk-dev] [PATCH v2] net/ice: support mark only action for FDIR

[Simei Su <simei.su@intel.com>]

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")
Cc: stable@dpdk.org
