So was any decision reached on this issue - will FreeBSD changed to accept a packet on an
interface that is larger than the mtu on that interface?

If possible, I'd like to see the ability to enforce interface MTU for received packets preserved in a sysctl if it is removed for the default config... In other words, something like:

net.link.mtu_limits_received_pktsize = 0|1

Then, default it to 0 to preserve 4.x behavior.

what would this achieve?

Answering himself.. it MAY allow a driver to optimise a bit by not needing to 
cope
with the posibility of receiving jubo packets?
I can not think of any other reason.. (except to break networks that are apparently working fine).


Thanks,
