Specifies the STP-bridge priority; the valid values are 0, 4096 , 8192 , 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152
Im using bridge filter to do QoS on these kinda traffic by protocol as i have mpls switching on that router, so only way to give pppoe less priority on AP side is to mark traffic by protocol type:
eg
pppoe = prio 8
ip = prio 1
36864 = prio 1 for now ( dunno what mac-protocol is)
vlan = prio 3
