Is there any plan to raise supported ethernet mtu above 1500 ?
Currently, packets are dropped above this point.
Even 802.1q tags require explicitly lowering the mtu to 1496 to work.

I thought the IP layer was supposed to fragment packets if they do not
fit in the underlying ethernet's MTU.

(What's the point about fragmentation, otherwise?)
