lagg failover issue

[kaltheat at googlemail.com]

Hi,

I'm using following devices:

bge0 - NetLink BCM57780 Gigabit Ethernet PCIe
ndis0 - BCM43225 802.11b/g/n

As far as I've tested it, each of them work fine for itself.

I want to aggregate them using lagg in failover mode as explained here[1][2]. 
But when I remove the wire (wireless connection is established), I can't put 
any traffic through lagg0.

What might be the problem? Can you give me some hints on how to debug this 
lagg-issue further?

Regards,
kaltheat
