struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.
Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address
from driver private storage rather than sometimes being ac_enaddr.

and into the bus front ends. For ISA and C-BUS cards, we always need
to grab it. For PC Card, already committed, we need to do some sanity
checking on the data that's in the ROMs before we decide that they are
OK to use. The PC Card code has already been committed and is
independent of this code (which also has to work on NE-1000 cards,
assuming that those cards still work :-).
and wd80x3 support. Make the obscure ISA cards optional, and add
those options to NOTES on i386 (note: the ifdef around the whole code
is for module building). Tweak pc98 ed support to include wd80x3 too.
Add goo for alpha too.
The affected cards are the 3Com 3C503, HP LAN+ and SIC (whatever that
is). I couldn't find any of these for sale on ebay, so they are
untested. If you have one of these cards, and send it to me, I'll
ensure that you have no future problems with it...
Minor cleanups as well by using functions rather than cut and paste
code for some probing operations (where the function call overhead is
lost in the noise).
Remove use of kvtop, since they aren't required anymore. This driver
needs to get its memory mapped act together, however, and use bus
space. It doesn't right now.
This reduces the size of if_ed.ko from about 51k to 33k on my laptop.
if_ed and rename it to ed_detach(). Tell other busses to use this
routine for detach.
Since I don't actually have any non-pccard ed hardware I can test
with, I've only tested with my pccards.
More improvements in this area likely are possible.

if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.
This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

NOTE: We must put ed_probe_SIC() function into if_ed_isa.c because
this is a bus dependent code. But the ed driver code is not
separated explicitly whether it is bus dependent or independent
now.

- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)
o Move the ax88190 code to its own function.
o Move all device_method_t, driver_t and DRIVER_MODULE definitions to the
end of files.
o Wrap a few lines > 80 characters.
o Use the same devclass for all ed drivers. This allows machines with
multiple types of cards to have their cards numbered correctly. Before,
you could wind up with two ed0's.
o Protect if_edvar.h from multiple includes because I was there.
