special-purpose code to display status for an interface for state that was not address-oriented. This status reporting was merged in to the address-oriented status reporting but did not work for link address reporting (as discovered with fwip interfaces). Correct this mis-merge and eliminate the bogus kludge that was used for link-level address reporting. o add an af_other_status method for an address family for reporting status of things like media, vlan, etc. o call the af_other_status methods after reporting address status for an interface o special-case link address status; when reporting all status for an interface invoke it specially prior to reporting af_other_status methods (since it requires the sockaddr_dl that is passed in to status separately from the rtmsg address state) o correct the calling convention for link address status; don't cast types, construct the proper parameter This fixes ifconfig on fwip interfaces.
