Author: melifaro Date: Sun Nov 29 13:52:06 2020 New Revision: 368149 URL: https://svnweb.freebsd.org/changeset/base/368149
Log: Add nhop_ref_any() to unify referencing nhop or nexthop group. It allows code within routing subsystem to transparently reference nexthops and nexthop groups, similar to nhop_free_any(), abstracting ROUTE_MPATH details.
