o Restore netmap emulation mode to working order, including
fixing the destructor panics on detach.
o Omit pipe additions to these fixes, likely problematic for
Suricata to pass traffic like it does on 11.0 without this
patch.
o Allow to build the module without errors in the tree.
Many thanks to Vincenzo Maffione for assistance and review! :)

Subject: [PATCH] freebsd: generic: call m_extadd() only once for each mbuf
Plug leak in m_unshare.
m_unshare passes on the source mbuf's flags as-is to m_getcl and this
results in a leak if the flags include M_NOFREE. The fix is to clear
the bits not listed in M_COPYALL before calling m_getcl. M_RDONLY
should probably be filtered out too but that's outside the scope of this
fix.
Add assertions in the zone_mbuf and zone_pack ctors to catch similar
bugs.
Update netmap_get_mbuf to not pass M_NOFREE to m_getcl. It's not clear
what the original code was trying to do but it's likely incorrect.
Updated code is no different functionally but it avoids the newly added
assertions.
