I am trying to run QEMU on a fairly recent snapshot of HEAD, but it failed with:
# DISPLAY=:0 qemu -win2k-hack -hda windows.img -boot c -net nic -net tap
bridge0: creating bridge interface
ifconfig: SIOCIFCREATE2: Invalid argument
/etc/qemu-ifup: ERROR: bridge0: failed to create
/etc/qemu-ifup: could not launch network script
Could not initialize device 'tap'
#
At about the same time, `ifconfig bridge0 create' fails with:
Aug 12 09:36:58 gothmog kernel: KLD if_bridge.ko: depends on bridgestp - not available
Aug 12 09:36:58 gothmog giorgos: /etc/qemu-ifup: ERROR: bridge0: failed to create
Aug 12 09:37:17 gothmog kernel: KLD if_bridge.ko: depends on bridgestp - not available
Aug 12 09:48:25 gothmog kernel: KLD if_bridge.ko: depends on bridgestp - not available
Aug 12 09:48:49 gothmog kernel: KLD if_bridge.ko: depends on bridgestp - not available
It appears to have been caused by src/sys/net/if.h revision 1.261:
date: 2006/07/09 06:04:00; author: sam; state: Exp; lines: +6 -3
Revise network interface cloning to take an optional opaque
parameter that can specify configuration parameters:
o rev cloner api's to add optional parameter block
o add SIOCCREATE2 that accepts parameter data
o rev vlan support to use new api (maintain old code)

Any idea how if_bridge can be fixed again?
