Add support for offloading learning and broadcast flooding flags. With this in place, mv88e6xx supports offloading of all bridge port flags that are currently supported by the bridge.
Broadcast flooding is somewhat awkward to control as there is no per-port bit for this like there is for unknown unicast and unknown multicast. Instead we have to update the ATU entry for the broadcast address for all currently used FIDs. v1 -> v2: - Ensure that mv88e6xxx_vtu_get handles VID 0 (Vladimir) - Fixed off-by-one in mv88e6xxx_port_set_assoc_vector (Vladimir) - Fast age all entries on port when disabling learning (Vladimir) - Correctly detect bridge flags on LAG ports (Vladimir) Tobias Waldekranz (8): net: dsa: Add helper to resolve bridge port from DSA port net: dsa: mv88e6xxx: Avoid useless attempts to fast-age LAGs net: dsa: mv88e6xxx: Provide generic VTU iterator net: dsa: mv88e6xxx: Remove some bureaucracy around querying the VTU net: dsa: mv88e6xxx: Use standard helper for broadcast address net: dsa: mv88e6xxx: Flood all traffic classes on standalone ports net: dsa: mv88e6xxx: Offload bridge learning flag net: dsa: mv88e6xxx: Offload bridge broadcast flooding flag drivers/net/dsa/mv88e6xxx/chip.c | 272 ++++++++++++++++++++++--------- drivers/net/dsa/mv88e6xxx/port.c | 21 +++ drivers/net/dsa/mv88e6xxx/port.h | 2 + include/net/dsa.h | 14 ++ net/dsa/dsa_priv.h | 14 +- 5 files changed, 234 insertions(+), 89 deletions(-) -- 2.25.1
