+/**
+ * ocelot_update_vlan_reclassify_rule() - Make switch aware only to bridge VLAN TPID
+ *
+ * @ocelot: Switch private data structure
+ * @port: Index of ingress port
+ *
+ * IEEE 802.1Q-2018 clauses "5.5 C-VLAN component conformance" and "5.6 S-VLAN
+ * component conformance" suggest that a C-VLAN component should only recognize
+ * and filter on C-Tags, and an S-VLAN component should only recognize and
+ * process based on C-Tags.
+ *
+ * In Linux, as per commit 1a0b20b25732 ("Merge branch 'bridge-next'"), C-VLAN
+ * components are largely represented by a bridge with vlan_protocol 802.1Q,
+ * and S-VLAN components by a bridge with vlan_protocol 802.1ad.
+ *
+ * Currently the driver only offloads vlan_protocol 802.1Q, but the hardware
+ * design is non-conformant, because the switch assigns each frame to a VLAN
+ * based on an entirely different question, as detailed in figure "Basic VLAN
+ * Classification Flow" from its manual and reproduced below.
+ *
+ * Set TAG_TYPE, PCP, DEI, VID to port-default values in VLAN_CFG register
+ * if VLAN_AWARE_ENA[port] and frame has outer tag then:
+ *   if VLAN_INNER_TAG_ENA[port] and frame has inner tag then:
+ *     TAG_TYPE = (Frame.InnerTPID <> 0x8100)
+ *     Set PCP, DEI, VID to values from inner VLAN header
+ *   else:
+ *     TAG_TYPE = (Frame.OuterTPID <> 0x8100)
+ *     Set PCP, DEI, VID to values from outer VLAN header
+ *   if VID == 0 then:
+ *     VID = VLAN_CFG.VLAN_VID
+ *
+ * Summarized, the switch will recognize both 802.1Q and 802.1ad TPIDs as VLAN
+ * "with equal rights", and just set the TAG_TYPE bit to 0 (if 802.1Q) or to 1
+ * (if 802.1ad). It will classify based on whichever of the tags is "outer", no
+ * matter what TPID that may have (or "inner", if VLAN_INNER_TAG_ENA[port]).
+ *
+ * In the VLAN Table, the TAG_TYPE information is not accessible - just the
+ * classified VID is - so it is as if each VLAN Table entry is for 2 VLANs:
+ * C-VLAN X, and S-VLAN X.
+ *
+ * Whereas the Linux bridge behavior is to only filter on frames with a TPID
+ * equal to the vlan_protocol, and treat everything else as VLAN-untagged.
+ *
+ * Consider an ingress packet tagged with 802.1ad VID=3 and 802.1Q VID=5,
+ * received on a bridge vlan_filtering=1 vlan_protocol=802.1Q port. This frame
+ * should be treated as 802.1Q-untagged, and classified to the PVID of that
+ * bridge port. Not to VID=3, and not to VID=5.
+ *
+ * The VCAP IS1 TCAM has everything we need to overwrite the choices made in
+ * the basic VLAN classification pipeline: it can match on TAG_TYPE in the key,
+ * and it can modify the classified VID in the action. Thus, for each port
+ * under a vlan_filtering bridge, we can insert a rule in VCAP IS1 lookup 0 to
+ * match on 802.1ad tagged frames and modify their classified VID to the 802.1Q
+ * PVID of the port. This effectively makes it appear to the outside world as
+ * if those packets were processed as VLAN-untagged.
+ *
+ * The rule needs to be updated each time the bridge PVID changes, and needs
+ * to be deleted if the bridge PVID is deleted, or if the port becomes
+ * VLAN-unaware.
