[Bug 230465] ixl: not working in netmap mode

(In reply to Kubilay Kocak from comment #38)

This is not a suricata issue. There was a suricata issue mentioned in this
thread, but it has been fixed upstream (suricata).

Comment #37 seems unrelated, since it mentions netmap with ixl in 12.x, where
iflib is in use. There was an iflib/netmap bug (see
https://reviews.freebsd.org/D25252) that may explain the problems briefly
mentioned in #37. But that is now in HEAD and stable/12.

This report is about a bug that apparently affects netmap TX over ixl in 11.x
(but not in 12.x and ahead).
This change
https://reviews.freebsd.org/D18984
does some cleanup but it does not fix the bug.
As you can see in the discussion, I reported the issue to the Intel developers,
but as far as I know there have been no changes on their side (in stable/11).
So I can assume that the bug is still there, and it's something that need the
Intel developers attention, if someone is still interested in netmap+ixl in
11.x
