if_bridge problem

[Gema niskazhu]

Hi

First of all sorry for my bad english =)

I am running 7.0 STABLE

So...I've build a kernel with device if_bridge, and if_bridge and tap are
kldload'ed, tap0 bridge0 are up'ed..but...

sysctl net.link.ether.bridge_cfg=nfe0,tap0

I have error:sysctl: unknown oid 'net.link.ether.bridge_cfg'

# sysctl -a |grep bridge
net.link.bridge.ipfw: 0
net.link.bridge.log_stp: 0
net.link.bridge.pfil_local_phys: 0
net.link.bridge.pfil_member: 1
net.link.bridge.pfil_bridge: 1
net.link.bridge.ipfw_arp: 0
net.link.bridge.pfil_onlyip: 1

dev.hostb.0.%desc: Host to PCI bridge
dev.hostb.1.%desc: Host to PCI bridge
dev.hostb.2.%desc: Host to PCI bridge
dev.hostb.3.%desc: Host to PCI bridge


I can't understand execly what i'm doing wrong, looks like something still
is'nt kldloaded, or not supported by kernel, but i cant imagine what it
is...

Any suggestions?
