Subject: Consider /31 and /32 valid subnet masks.
X-Git-Url: https://git.proxmox.com/?p=pve-common.git;a=commitdiff_plain;h=e43faad9ff27f4d252d5604439c7aab1ff1c6251

Consider /31 and /32 valid subnet masks.

Since we already allow this for container IP addresses it is
reasonable to assume the host might be using such a setup as
well. (You can use an additional route to reach the gateway
and then simply have no "LAN".) Some people seem to want
this...
