Yes

No. It looks like the macros work with more
than one structure: svc and dest. Same was for CHECK_PE
where both structs were supported: ipvs_service_entry_t and
ipvs_service_t when CHECK_PE was called from CHECK_COMPAT_SVC.
CHECK_COMPAT_SVC does not check the dest->af,
it checks svc->af. Without both checks, svc can come
with address from AF_INET family while -r option has address
from AF_INET6 family. IMHO, we need just the return->goto
change.
