-Subject: [PATCH] net: dsa: b53: Do not force CPU to be always tagged
-
-Commit ca8931948344 ("net: dsa: b53: Keep CPU port as tagged in all
-VLANs") forced the CPU port to be always tagged in any VLAN membership.
-This was necessary back then because we did not support Broadcom tags
-for all configurations so the only way to differentiate tagged and
-untagged traffic while DSA_TAG_PROTO_NONE was used was to force the CPU
-port into being always tagged.
-
-With most configurations enabling Broadcom tags, especially after
-8fab459e69ab ("net: dsa: b53: Enable Broadcom tags for 531x5/539x
-families") we do not need to apply this unconditional force tagging of
-the CPU port in all VLANs.
-
-A helper function is introduced to faciliate the encapsulation of the
-specific condition requiring the CPU port to be tagged in all VLANs and
-the dsa_switch_ops::untag_bridge_pvid boolean is moved to when
-dsa_switch_ops::setup is called when we have already determined the
-tagging protocol we will be using.
