[dpdk-dev] [PATCH] net/ice: fix FDIR PASSTHRU issue

[Yahui Cao <yahui.cao@intel.com>]

The original PASSTHRU implementation is forwarding to queue 0. The
corrected implementation is forwarding to the next stage filter.

Fixes: f5cafa961fae ("net/ice: add flow director create and destroy")
Cc: stable@dpdk.org
