As a workaround you can switch to the emulated network card by
setting 'hw.xen.disable_pv_nics=1' in /boot/loader.conf. That will
give you worse performance than a fully working PV network card, but
at least should be consistent. There are others that have switched to
virtio-net, but I have no idea how to do that with XCP.
Just to add my $0.02's to the conversation...
As Roger knows we've had numerous issues with Xen xn based networking and
FreeBSD guests over the years. We currently run VirtIO (vtnet) on XenServer
7.1 and it solves all these issues (it's probably not quite as 'performant'
as xn - but it's close for what we're using it with - it is miles better
than e1000 performance).
Unfortunately in XenServer 7.6 virtio is no longer compiled into Qemu from
what I can see. XCP-ng has the same issue (as it's based on XenServer) - so
virtio is currently not an option with XCP-ng either.
e1000/rtl8139 will solve 'weirdness' (think of VM's routing traffic, doing
DHCP or VPN duties) - but virtio solves the same issues, with much better
performance.
I've posted to the XCP-ng forums asking if virtio can be enabled in XCP-ng
builds (as this is probably more likely that getting XenServer to release
with it enabled).
Aside from getting Xen xn 'fixed' for the cases it currently fails (no
small undertaking from what I understand) - it leaves FreeBSD pretty much
stuck, at least for some usage cases.
