Yes netmap(4) is a built-in and default feature on FreeBSD. netmap
package from ports is not related to it.
BTW, I haven't tried qemu's netmap feature on FreeBSD. Is there
anything we can test this more?
This is an example command line for a qemu VM with a vtnet interface connected to a port of a VALE switch called 'vale1':
qemu-system-x86_64 fbsd-head.qcow2 -smp 2 -m 2G -vga std -device e1000,netdev=mgmt,mac=00:AA:BB:CC:0a:99 -netdev user,id=mgmt,hostfwd=tcp::20010-:22 -device virtio-net-pci,netdev=data10,mac=00:AA:BB:CC:0a:0a,ioeventfd=on,mrg_rxbuf=on -netdev netmap,ifname=vale1:10,id=data10
