9 * The VLAN and bridge model the GSWIP hardware uses does not directly
10 * matches the model DSA uses.
12 * The hardware has 64 possible table entries for bridges with one VLAN
13 * ID, one flow id and a list of ports for each bridge. All entries which
14 * match the same flow ID are combined in the mac learning table, they
15 * act as one global bridge.
16 * The hardware does not support VLAN filter on the port, but on the
17 * bridge, this driver converts the DSA model to the hardware.
19 * The CPU gets all the exception frames which do not match any forwarding
20 * rule and the CPU port is also added to all bridges. This makes it possible
21 * to handle all the special cases easily in software.
22 * At the initialization the driver allocates one bridge table entry for
23 * each switch port which is used when the port is used without an
24 * explicit bridge. This prevents the frames from being forwarded
25 * between all LAN ports by default.
