[ Upstream commit c2bf23e4a5af37a4d77901d9ff14c50a269f143d ]
Filters on different vports are qualified by different implicit MACs and/or
VLANs, so shouldn't be considered equal even if their other match fields
are identical.
Fixes: 7c460d9be610 ("sfc: Extend and abstract efx_filter_spec to cover Huntington/EF10")
