I don't know whether the Atheros stuff does (I think it does, but I
don't know under what conditions it's possible.)
Maybe have it by default not return jumbo mbufs, and if a driver wants
jumbo mbufs it can explicitly ask for them.
Jumbo frames do not see wide-spread use. If they are used, then
in data centre LAN environments and possibly also inter-datacenter.
That is high performance environments.
I seriously doubt that lower-end ethernet MACs you're referring to
fit that bill.
