* why does kernel 3.8-rc1 put all TAP devices into state RUNNING during boot

At my stable Gentoo Linux I'm observed a change behaviour for the
configured TAP devices after the boot process.

$ diff 3.7.1 3.8.0-rc1+ | grep UP
< br0: flags=4355<UP,BROADCAST,PROMISC,MULTICAST>  mtu 1500
> br0: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST>  mtu 1500
< tap0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
> tap0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500


May I ask you if this changed behaviour is intended ?


FWIW I configured those devices at that system in this way :

$ head -n 20 /etc/conf.d/net
# /etc/conf.d/net
#

#       KVM
#
bridge_br0="tap0 tap1 tap2 tap3"
config_br0="192.168.0.254/8"
brctl_br0="setfd 0
sethello 10
stp off"
rc_net_br0_need="net.tap0 net.tap1 net.tap2 net.tap3"

config_tap0="null"
tuntap_tap0="tap"
tunctl_tap0="-u <me>"

...

I'm not aware of any changes in this behavior.
btw Looks like it changed for your bridge interfaces as well. So it's not really
specific to the TAP devices.

Someone from netdev would know :)
