[dpdk-dev] [PATCH v1] net/i40e: fix qinq flow pattern to allow non full mask

Issue reported by customer that only full mask was allowed on inner and outer
VLAN tag, thus not allowing mask to set VLAN ID filter only. Removed check that
enforces inner vlan and outer vlan equal I40E_TCI_MASK (full mask 0xffff).

Fixes: c2be7f9b232f ("net/i40e: fix parsing QinQ pattern")
Fixes: d37705068ee8 ("net/i40e: parse QinQ pattern")
