0ee3222df6 Roll my own min() (named ISO88025_MIN() so as to not cause conflicts) so
that this header may be included from userland where min() may not be
declared (or worse, declared differently).  I open to alternative
solutions.

42fdfc126a 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).  Further
refinements could overcome this limitation but would break binary
compatibility; this commit only addresses fixing the bug for
commonly-occuring cases without breaking binary compatibility with the
intention that the functionality can be MFC'ed to -stable.

09efa444d5 - Define payload length constants for 4Mbps and 16Mbps.
- Use explicit sizes for header structure fields.
- Use __attribute__ ((__packed__)) for header structures.
- Define struct iso88025_rif; for future use.
- Prototype upcoming iso88025_ifdetach()
- Get rid of __P() constructs in prototypes.

b149dd6c66 o Replace most magic numbers related to token ring with #defines
from iso88025.h.

o Add minimal llc support to iso88025_input.

o Clean up most of the source routing code.

Move the Olicom token ring driver to the officially sanctionned location of
/sys/contrib. Also fix some brokenness in the generic token ring support.

Be warned that if_dl.h has been changed and SOME programs might
like recompilation.

722012cc0c World, I'd like you to meet the first FreeBSD token Ring driver.
This  is for various Olicom cards. An IBM driver is following.
This patch also adds support to tcpdump to decode packets on tokenring.
Congratulations to the proud father.. (below)
