This patchset fixes hardware bridging for non 802.1Q aware systems. The mv88e6xxx DSA driver currently depends on CONFIG_VLAN_8021Q and CONFIG_BRIDGE_VLAN_FILTERING enabled for correct bridging between switch ports.
Patch 1/9 adds support for the VLAN filtering switchdev attribute in DSA. Patchs 2/9 and 3/9 add helper functions for the following patches. Patchs 4/9 to 6/9 assign dynamic address databases to VLANs, ports, and bridge groups (the lowest available FID is cleared and assigned), and thus restore support for per-port FDB operations. Patchs 7/9 to 9/9 refine ports isolation and setup 802.1Q on user demand. With this patchset, ports get correctly bridged and the driver behaves as expected, with or without 802.1Q support. With CONFIG_VLAN_8021Q enabled, setting a default PVID to the bridge correctly propagates the corresponding VLAN, in addition to the hardware bridging: # echo 42 > /sys/class/net/<bridge>/bridge/default_pvid But considering CONFIG_BRIDGE_VLAN_FILTERING enabled, the hardware VLAN filtering is enabled on all bridge members only when the user requests it: # echo 1 > /sys/class/net/<bridge>/bridge/vlan_filtering Vivien Didelot (9): net: dsa: support VLAN filtering switchdev attr net: dsa: mv88e6xxx: extract single VLAN retrieval net: dsa: mv88e6xxx: extract single FDB dump net: dsa: mv88e6xxx: assign dynamic FDB to VLANs net: dsa: mv88e6xxx: assign default FDB to ports net: dsa: mv88e6xxx: assign dynamic FDB to bridges net: dsa: mv88e6xxx: restore VLANTable map control net: dsa: mv88e6xxx: remove reserved VLANs net: dsa: mv88e6xxx: support VLAN filtering drivers/net/dsa/mv88e6171.c | 1 + drivers/net/dsa/mv88e6352.c | 1 + drivers/net/dsa/mv88e6xxx.c | 441 ++++++++++++++++++++++++++++++++++---------- drivers/net/dsa/mv88e6xxx.h | 6 + include/net/dsa.h | 2 + net/dsa/slave.c | 21 +++ 6 files changed, 370 insertions(+), 102 deletions(-) -- 2.7.1
