Description:

When I try to bring up a network bridge with a physically disconnected interface to be added, i get:
>no connection
and bridge doesn't brings up. As far as i know that's because netcfg calls /lib/network/connections/bridge that calls /lib/network/connections/ethernet for every interface supposed to be added to a bridge. /lib/network/connections/ethernet checks if interface physically connected and does nothing if it's not. I think such behavior is wrong for bridges because if you have more than one nics in bridge (you will have at least 2 or you doesn't need bridging) this is actually prevents all the connected ones from bringing up.


Additional info:

* package version(s)
netcfg 2.8.11-2 and probably older 2.8 versions
netcfg 3.0 - bridge created but it's down and has no IP

* config and/or log files etc.
INTERFACE="br0"
CONNECTION="bridge"
BRIDGE_INTERFACES="eth0"
IP="static"
ADDR="192.168.42.1"
NETMASK="23"
Another nic (wlan0) is added by hostapd so there is only one


Steps to reproduce:

1. Make a simple config:
INTERFACE="br0"
CONNECTION="bridge"
BRIDGE_INTERFACES="eth0"
IP="static"
ADDR="192.168.0.1"
NETMASK="24"
and save as /etc/network.d/br0

2. Disconnect network cable from nic if present

3. Try to bring up a bridg with
# netcfg br0

4. No profit.
