although this version has been changed somewhat: - reference counting on ifaddrs isn't as complete as Bill's original work was. This is hard to get right, and we should attack one protocol at a time. - This doesn't do reference counting or dynamic allocation of ifnets yet. - This version introduces a new PRU -- PRU_PURGEADDR, which is used to purge an ifaddr from a protocol. The old method Bill used didn't work on all protocols, and it only worked on some because it was Very Lucky. This mostly works ... i.e. works for my USB Ethernet, except for a dangling ifaddr reference left by the IPv6 code; have not yet tracked this down.
In case you were wondering why this code is still present: The ISO (or OSI) stack is still in use by many router vendors (e.g., using IS-IS the OSI equivelent of OSPF, to carry IP routes). Chris. chopps@netbsd.org
