+ * kernel_socket.c: consolidate the IFAM{ADDR,MASK}GET and
+ RTM{ADDR,MASK}GET macros into generic rta_addrs macros,
+ RTA_{ADDR,ATTR}_GET.
+ (af_check) could use 'inline' attribute
+ (ifam_read_mesg) remove IFAM{ADDR,MASK}GET macro, change to
+ generic macro.
+ (rtm_read_mesg) similar

* rt_netlink.c: Remove netlink-addr socket declaration, it's not used.
