[zebra/solaris] Interface state fixups for Solaris.

2006-01-25 Paul Jakma <paul.jakma@sun.com>

	* (general) More solaris PF_ROUTE hacks. The IFF_UP mangling
	  for solaris was incomplete on the PF_ROUTE side. fix it.
	  This changeset generally uglifies things. For some future
	  work I'd like to see the state changes seperated out from
	  the details of the code. Differences between systems might
	  then be slightly easier to implement without convoluted
	  hacks.
	  Changes should be specific to Solaris mostly, however
	  also tested on FreeBSD 6.
	* if_ioctl_solaris.c: (interface_list_ioctl) ignore ~IFF_UP
	  interfaces, we'll hear about them when/if interface goes up
	  through NEWADDR.
	  Update flags explicitely at end of it to kick mangling.
	* ioctl_solaris.c: (if_mangle_up) removed to interface.c, in
	  kind.
	  (lifreq_set_name) more convenient to take the string, than
	  the ifp.
	  (if_get_flags_direct) new convenience function, returns
	  the actual flags. Used during bootstrap in if_ioctl_solaris.c
	  to peek at flags of logical interfaces to see whether or
	  not to ignore them.
	  (if_get_flags) ENXIO means it's gone, poke out IFF_UP and
	  kick flags update.
	  (if_{un,}set_flags) flags argument should be 64bit.
	* ioctl.{c,h}: flags argument should be 64bit.
	* interface.h: Add a 'primary_state' flag to struct zebra_if on
	  SUNOS_5.
	  Export if_flags_update.
	* interface.c: (if_flags_mangle) moved over in kind from
	  ioctl_solaris.c. Nasty kludge to try get IFF_UP right, as
	  much as is possible. Also keep track of the actual IFF_UP
	  value for the primary interface, so we can know when the ifp
	  must be deleted.
	  (if_flags_update) Take a new interface flags value, apply it
	  to the interface, and take whatever actions are required due
	  to flag transitions.
	  (if_refresh) flag state change logic is moved out to
	  previous. Just call if_get_flags, which will end up using
	  previous to effect the update of flags.
	  (if_flag_dump_vty) IFF_IPV{4,6} aren't interesting, VIRTUAL
	  and NOXMIT are though.
	* kernel_socket.c: (ifm_read) Down->Down transitions shouldn't
	  create ifp, for non-IFANNOUNCE systems.
	  Use if_flags_update to update flags.
	  flag transition logic is now handled automatically through
	  if_flags_update.
	  (ifam_read) Better to call if_refresh *after* adding
 	  connected addresses, as connected count affects IFF_UP on
 	  IFF_UP-mangled systems.
 	  On Solaris, Up->Down due to DELADDR means we need to delete
	  the ifp - the IFINFO might already have been and gone.
	* rt.h: include other dependent headers.
