Subject: [dpdk-dev] [PATCH] net/iavf: fix FDIR ID parsing issue after queue reconfigured

FDIR ID parsing will not be handled correctly after queue reconfigured, enable FDIR ID parsing per Q regardless of fdir_ref_cnt to fix it.

Fixes: f71dbf852d46 ("net/iavf: add flow director enabled switch value")
