bgpd: optimize bgp_nexthop_self()
This function scores 2nd, profiling a full internet table load. It's called for every prefix received. Instead of looping in the interface lists comparing addresses use a hash to mantain them. * bgpd.c: Init the own address hash. * bgp_nexthop.c: Introduce methods to maintain an own address hash. (bgp_connected_add) add addresses to the hash. (bgp_connected_delete) delete addresses from the hash. (bgp_nexthop_self) lookup addresses in the hash. Removed the unused afi_t parameter. * bgp_route.c: (bgp_update_main) Micro-optimization, rearranged condition to not lookup the hash for bogus nexthops (0.0.0.0 or a class D/E address) Signed-off-by: Jorge Boncompte [DTI2] <jorge@dti2.net> Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
