[ Upstream commit 9f9581ba74 ]
While updating the binary min-len implementation, I noticed that
the only user, should AFAICT be using exact-len instead.
In net/ipv4/fou_core.c FOU_ATTR_LOCAL_V6 and FOU_ATTR_PEER_V6
are only used for singular IPv6 addresses, and there are AFAICT
no known implementations trying to send more, it therefore
appears safe to change it to an exact-len policy.
This patch therefore changes the local-v6/peer-v6 attributes to
use an exact-len check, instead of a min-len check.
