net: dsa: mv88e6xxx: add hardware VLAN support
This patchset brings support to access hardware VLAN entries in DSA and
mv88e6xxx, through switchdev VLAN objects.
In the following example, ports swp[0-2] belong to bridge br0, and ports
swp[3-4] belong to bridge br1. Here's an example of what can be achieved
after this patchset:
# bridge vlan add dev swp1 vid 100 master
# bridge vlan add dev swp2 vid 100 master
# bridge vlan add dev swp3 vid 100 master
# bridge vlan add dev swp4 vid 100 master
# bridge vlan del dev swp1 vid 100 master
The above commands correctly programmed hardware VLAN 100 for port swp2,
while ports swp3 and swp4 use software VLAN 100, as shown with:
# bridge vlan
port vlan ids
swp0 None
swp0
swp1 None
swp1
swp2 100
swp2 100
swp3 100
swp3
swp4 100
swp4
br0 None
br1 None
Assuming that port 5 is the CPU port, the hardware VLAN table would
contain the following data:
VID FID SID 0 1 2 3 4 5 6
100 8 0 x x t x x t x
Where 'x' means excluded, and 't' means tagged.
Also, adding an FDB entry to VLAN 100 for port swp2 like this:
# bridge fdb add 3c:97:0e:11:6e:30 dev swp2 vlan 100
Would result in the following example output:
# bridge fdb
# 01:00:5e:00:00:01 dev eth0 self permanent
# 01:00:5e:00:00:01 dev eth1 self permanent
# 00:50:d2:10:78:15 dev swp0 master br0 permanent
# 00:50:d2:10:78:15 dev swp2 vlan 100 master br0 permanent
# 3c:97:0e:11:6e:30 dev swp2 vlan 100 self static
# 00:50:d2:10:78:15 dev swp3 master br1 permanent
# 00:50:d2:10:78:15 dev swp3 vlan 100 master br1 permanent
And the Address Translation Unit would contain:
DB T/P Vec State Addr
008 Port 004 e 3c:97:0e:11:6e:30
