+ * felix_update_tag_8021q_rx_rule - Update VCAP ES0 tag_8021q rule after
+ * vlan_filtering change
+ * @outer_tagging_rule: Pointer to VCAP filter on which the update is performed
+ * @vlan_filtering: Current bridge VLAN filtering setting
+ *
+ * Source port identification for tag_8021q is done using VCAP ES0 rules on the
+ * CPU port(s). The ES0 tag B (inner tag from the packet) can be configured as
+ * either:
+ * - push_inner_tag=0: the inner tag is never pushed into the frame
+ * (and we lose info about the classified VLAN). This is
+ * good when the classified VLAN is a discardable quantity
+ * for the software RX path: it is either set to
+ * OCELOT_STANDALONE_PVID, or to
+ * ocelot_vlan_unaware_pvid(bridge).
+ * - push_inner_tag=1: the inner tag is always pushed. This is good when the
+ * classified VLAN is not a discardable quantity (the port
+ * is under a VLAN-aware bridge, and software needs to
+ * continue processing the packet in the same VLAN as the
+ * hardware).
+ * The point is that what is good for a VLAN-unaware port is not good for a
+ * VLAN-aware port, and vice versa. Thus, the RX tagging rules must be kept in
+ * sync with the VLAN filtering state of the port.
