Hi all,
This patchset brings full support for hardware VLANs in DSA, and the Marvell
88E6352 and compatible switch chips.
Patches 1/4 to 3/4 are ready to be applied. However, patch 4/4 brought some
concerns about the management of the forwarding database [1]. That might be
updated in future patches though.
Below is an example of what can be done with this patchset.
"VID 550: 1t 3u"
"VID 1000: 2t"
"VID 1200: 2t 4t"
The VLAN setup above can be achieved with the following bridge commands:
bridge vlan add vid 550 dev swp1 master
bridge vlan add vid 550 dev swp3 master untagged pvid
bridge vlan add vid 1000 dev swp2 master
bridge vlan add vid 1200 dev swp2 master
bridge vlan add vid 1200 dev swp4 master
Removing the port 1 from VLAN 550 is done with:
bridge vlan del vid 550 dev swp1
The bridge command would output the following setup:
# bridge vlan
port vlan ids
swp0 None
swp0
swp1 None
swp1
swp2 1000
1200
swp2 1000
1200
swp3 550 PVID Egress Untagged
swp3 550 PVID Egress Untagged
swp4 1200
swp4 1200
br0 None
Assuming that swp5 is the CPU port, the "vtu" debugfs file would show:
# cat /sys/kernel/debug/dsa0/vtu
VID FID SID P0 P1 P2 P3 P4 P5 P6
550 562 0 x x x u x t x
1000 1012 0 x x t x x t x
1200 1212 0 x x t x t t x
Cheers,
