We return the VLAN table size through devlink as a simple parameter, we do not support altering it at runtime: devlink resource show mdio_bus/fixed-0:1f mdio_bus/fixed-0:1f: name VTU size 4096 occ 0 unit entry dpipe_tables none and after configure a bridge with VLAN filtering: devlink resource show mdio_bus/fixed-0:1f mdio_bus/fixed-0:1f: name VTU size 4096 occ 1 unit entry dpipe_tables none Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> --- drivers/net/dsa/dsa_loop.c | 55 +++++++++++++++++++++++++++++++++++++- 1 file changed, 54 insertions(+), 1 deletion(-)
