[pve-devel] dhcp : lease a mask with 255.255.255.255 is not possible

[Dietmar Maurer]

OK, thanks for the links.

What I observed recently that dhcp with dmsmaq does not work with virtio,
but works perfectly with e1000.

Maybe that is related, because virtio uses TSO, but e1000 not.

But dhcp with our Windows server works without problems, so maybe it
is related to dnsmasq?
