Log:
MFC netinet/if_ether.c:1.93-1.94,
net/if_iso88025subr.c:1.21,
net/iso88025.h:1.6-1.8:
Move ISO88025 source routing information into sockaddr_dl's
sdl_data field. This returns the sdl_data field to a
variable-length field. More importantly, this prevents a
easily-reproduceable data-corruption bug when the interface name
plus the hardware address exceed the sdl_data field's original 12
byte limit. However, token-ring interfaces may still overflow the
new sdl_data field's 46 byte limit if the interface name exceeds 6
characters (since 6 characters for interface name plus 6 for hardware
address plus 34 for source routing = the size of sdl_data).
