Support for fragmented packets with ixgbe was recently added on the linux version of Netmap :

https://github.com/luigirizzo/netmap/commit/fc1e77560a8a8ea93cc3594de5fae94334debcd3

I think the change for freebsd would be quite the same looking at https://github.com/freebsd/freebsd/blob/master/sys/dev/netmap/ixgbe_netmap.h#L396

After that, your userspace application simply have to check for the NS_MOREFRAG flag in the receive ring, and if it's set he knows the end of the packet will follow in the next buf.
