It means that the network cards are entering promiscous mode, which in 
turn means it will pick all packets that passes its physical layer and 
then the bridge code will forward it to the other interface. _however_ 
lnc2 should not enter promiscous mode if its not a part of the bridge?

Post what version you're using and the rest of your sysctl statements for 
the bridge, also is it the kernel module or compiled in kernel?

(Maybe you'll have more luck with this in the freebsd-net list?)
