Subject: [dpdk-dev] [PATCH v3] net/i40e: fix qinq flow pattern to allow non full mask
Date: Thu, 15 Oct 2020 10:28:58 +0100	[thread overview]
Message-ID: <20201015092858.84731-1-padraig.j.connolly@intel.com> (raw)
In-Reply-To: <20201014163047.69981-1>

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 thatenforces inner vlan and outer vlan equal
I40E_TCI_MASK (full mask 0xffff).

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