[dpdk-dev] [PATCH] net/i40e: fix fail to disable FDIR Tx queue

[dpdk-dev] [PATCH] net/i40e: fix fail to disable FDIR Tx queue

[Beilei Xing]

If flow directory is enabled, FDIR Tx queue can't
be disabled when exiting application. Root cause
is FDIR Tx queue is not disabled before removing
HMC backing store.

Fixes: 71d35259ff67 ("i40e: tear down flow director")
