            Bug ID: 284459
           Summary: if_ovpn: Undefined symbol "in6_sin6_2_sin_in_sock" if
                    IPv6 support is disabled
           Product: Base System
           Version: 14.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org

A kernel compiled without IPv6 support does cannot load if_ovpn.ko as it
requires does not cater of IPv6 mapped addresses  from IPv4.

Specifically, these lines are not defined for only INET6 support, which causes
the error. 

if (peer->local.ss_family == AF_INET6 &&
            IN6_IS_ADDR_V4MAPPED(&TO_IN6(&peer->remote)->sin6_addr)) {
                /* V4 mapped address, so treat this as v4, not v6. */
                in6_sin6_2_sin_in_sock((struct sockaddr *)&peer->local);
                in6_sin6_2_sin_in_sock((struct sockaddr *)&peer->remote);
        }

My suggestion is to move the #ifdef INET6 before this logic.

Note: This issue is also present on the main branch.
