I just document myself a bit better on VLAN and bridges.

After re-reading the datasheet, it seems to me that the OS can barely 
control address learning of the bridge. It can almost only control the 
aging, disable the learning, set hashing function, set MTU,... Same goes 
for VLANs. I can't find any reference for 802.1Q conformance in the 
datasheet. I'm not even sure the implementation is VLAN hoping safe. The 
routing description is pretty basic.
