lack of destination ports and MTU enforcement checks). Byte-level counters are
not available.
+Limitations
+===========
+
+The SJA1105 switch family always performs VLAN processing. When configured as
+VLAN-unaware, frames carry a different VLAN tag internally, depending on
+whether the port is standalone or under a VLAN-unaware bridge.
+
+The virtual link keys are always fixed at {MAC DA, VLAN ID, VLAN PCP}, but the
+driver asks for the VLAN ID and VLAN PCP when the port is under a VLAN-aware
+bridge. Otherwise, it fills in the VLAN ID and PCP automatically, based on
+whether the port is standalone or in a VLAN-unaware bridge, and accepts only
+"VLAN-unaware" tc-flower keys (MAC DA).
+
+The existing tc-flower keys that are offloaded using virtual links are no
+longer operational after one of the following happens:
+
+- port was standalone and joins a bridge (VLAN-aware or VLAN-unaware)
+- port is part of a bridge whose VLAN awareness state changes
+- port was part of a bridge and becomes standalone
+- port was standalone, but another port joins a VLAN-aware bridge and this
+ changes the global VLAN awareness state of the bridge
+
+The driver cannot veto all these operations, and it cannot update/remove the
+existing tc-flower filters either. So for proper operation, the tc-flower
+filters should be installed only after the forwarding configuration of the port
+has been made, and removed by user space before making any changes to it.

-/* RX VLAN tagging (left) and TX VLAN tagging (right) setup shown for a single
- * front-panel switch port (here swp0).
+/* There are 2 ways of offloading tag_8021q VLANs.
*
- * Port identification through VLAN (802.1Q) tags has different requirements
- * for it to work effectively:
- * - On RX (ingress from network): each front-panel port must have a pvid
- * that uniquely identifies it, and the egress of this pvid must be tagged
- * towards the CPU port, so that software can recover the source port based
- * on the VID in the frame. But this would only work for standalone ports;
- * if bridged, this VLAN setup would break autonomous forwarding and would
- * force all switched traffic to pass through the CPU. So we must also make
- * the other front-panel ports members of this VID we're adding, albeit
- * we're not making it their PVID (they'll still have their own).
- * - On TX (ingress from CPU and towards network) we are faced with a problem.
- * If we were to tag traffic (from within DSA) with the port's pvid, all
- * would be well, assuming the switch ports were standalone. Frames would
- * have no choice but to be directed towards the correct front-panel port.
- * But because we also want the RX VLAN to not break bridging, then
- * inevitably that means that we have to give them a choice (of what
- * front-panel port to go out on), and therefore we cannot steer traffic
- * based on the RX VID. So what we do is simply install one more VID on the
- * front-panel and CPU ports, and profit off of the fact that steering will
- * work just by virtue of the fact that there is only one other port that's
- * a member of the VID we're tagging the traffic with - the desired one.
+ * One is to use a hardware TCAM to push the port's standalone VLAN into the
+ * frame when forwarding it to the CPU, as an egress modification rule on the
+ * CPU port. This is preferable because it has no side effects for the
+ * autonomous forwarding path, and accomplishes tag_8021q's primary goal of
+ * identifying the source port of each packet based on VLAN ID.
*
- * So at the end, each front-panel port will have one RX VID (also the PVID),
- * the RX VID of all other front-panel ports that are in the same bridge, and
- * one TX VID. Whereas the CPU port will have the RX and TX VIDs of all
- * front-panel ports, and on top of that, is also tagged-input and
- * tagged-output (VLAN trunk).
+ * The other is to commit the tag_8021q VLAN as a PVID to the VLAN table, and
+ * to configure the port as VLAN-unaware. This is less preferable because
+ * unique source port identification can only be done for standalone ports;
+ * under a VLAN-unaware bridge, all ports share the same tag_8021q VLAN as
+ * PVID, and under a VLAN-aware bridge, packets received by software will not
+ * have tag_8021q VLANs appended, just bridge VLANs.
