Is netmap jumbo frames broken in STABLE?

[Vincenzo Maffione]

Hi,
  Yes, absolutely, I'm currently working on aligning netmap on FreeBSD
(head, stable/12 and stable/11) to
the same status it has on Linux (more features, more bugfixes, continuous
integration infrastructure ... ).
In particular, on Linux jumbo frames are already supported on ixgbe, e1000,
igb, e1000e, etc.

I have some netmap patches are already in the queue (see here
https://reviews.freebsd.org/differential/query/Ol8MNtAi2AIs/#R),
so I can address the ixgbe-jumbo-frames item as soon as the queue drains.
If you want to give a try in the meanwhile, and/or test ixgbe on FreeBSD it
would be great.

Cheers,
  Vincenzo
