--- Comment #19 from John Hartley <d...@graphica.com.au> ---
Tommy P & Matt S,
wound forward PCI code to 11.3 and network still working ok:
% find . -name '*.bak*' -print
./sbin/ipfw.bak
./sys/modules/mlx5en.bak
./sys/modules/netmap/Makefile.bak

All (non VirtIO network ok):

So this confirm that source of issue is in the /dev/netmap code.
I will try to wind this forward on a commit by commit basis to see where it
breaks.
Cheers,
John Hartley.
