Hello,

I created a FreeBSD 12.3 STABLE virtual router in a Proxmox 7.1 environment=
 and
was encountering this issue with my FreeBSD VM.=20
I can confirm that running the following helped to work arround the issue, =
but
the performance is terrible.

ifconfig vtnet0 -rxcsum
ifconfig vtnet1 -rxcsum

--=20
