Subject: RFS seems to have incompatiblities with bridged vlans

Hi,

i today tried out 2.6.32-rc2 and I see a lot of warning messages like this:

Jun  7 22:33:15 172.21.55.20 kernel: [ 3012.575884] br141 received packet on queue 4, but number of RX queues is 1

The host is a SMP system with 8 cores, so I think there is expected to be one rx queue per CPU, but it seems
the bridge iface has only one.

The br141 config looks like this:

#brctl show br141
bridge name	bridge id		STP enabled	interfaces
br141		8000.001018593cdc	no		eth2.141
							tap0
							tap2

The bridge is basically a bridge between a 802.1q vlan at eth2 and some tap Interfaces bound to
virtual machines on the system.

Peter.--
