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.
