| 2019-05-03 | net: dsa: sja1105: Add support for VLAN operations | Vladimir Oltean | 1 | -0/+38 | |
| VLAN filtering cannot be properly disabled in SJA1105. So in order to emulate the "no VLAN awareness" behavior (not dropping traffic that is tagged with a VID that isn't configured on the port), we need to hack another switch feature: programmable TPID (which is 0x8100 for 802.1Q). We are reprogramming the TPID to a bogus value which leaves the switch thinking that all traffic is untagged, and therefore accepts it. Under a vlan_filtering bridge, the proper TPID of ETH_P_8021Q is installed again, and the switch starts identifying 802.1Q-tagged traffic.

| 2019-05-03 | net: dsa: Introduce driver for NXP SJA1105 5-port L2 switch | Vladimir Oltean | 1 | -0/+949 | |
| At this moment the following is supported: * Link state management through phylib * Autonomous L2 forwarding managed through iproute2 bridge commands. IP termination must be done currently through the master netdevice, since the switch is unmanaged at this point and using DSA_TAG_PROTO_NONE.
