10-RC2 current wireless link aggregation not working correctly

Hi all,

I've set up wireless link aggregation on FreeBSD 10 RC1 and RC2 as
described in the FreeBSD handbook, on an oldish Compaq nc6320 laptop. 

What happens is:

If I boot the system with the Ethernet cable attached, I correctly get
lagg0 active port on master- bg0- and the network is working correctly.
(I mainly test pinging my gateway). When I pull the cable out, lagg0
device correctly switches to wlan0 as shown by ifconfig (wlan0 is created
from wpi0), but at the same time I get no more ping replies from my
gateway. I can leave the system in this state for several minutes as an
example
and no replies are coming through. A simple list of interfaces with
ifconfig with no parameters brigs the network back to life, and I start to
get back the due ping replyes, this time thrugh wireless link. 


Please, if possible en-light me on tis problem. I sat at your disposition
with any info you may deem necessary to get this fixed (if it needs a fix).
