Subject: [PATCH] net/sfc: cut non VLAN ID bits from TCI

[ upstream commit 8028142107a858a146bfdbaa010b7e77ff987342 ]

TCI may contain PCP or DEI bits. Matching of these bits is not
supported, but the bits still may be set in specification value and
not covered by mask. So, these bits should be ignored.

Fixes: 894080975e1e ("net/sfc: support VLAN in flow API filters")
