Break out obscure ISA cards into their own files, as well as ne2000 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.

Extricate probing of the gwether card (Gateway AT) from the middle of probing the novell ne[12]000 cards. It should be its own thing, ala how we do the dl100xx support doing its own thing at the right time. For the moment, it is just a function, which makes the mainline of the generic probe easier to follow. Also, correct a couple of comments that looked wrong. # there may be a bug in setting up gwether, in that we set # sc->rec_page_stop based on memsize, rather than sc->mem_size, so if # these two are different, then the rec_page_stop will be wrong. I'm # hesitant to fix it without real hardware to test with. Since # gwether isn't in the hardware list of the man page nor in the commit # messages, it is hard to know for sure.

Move the harvesting of the MAC address out of the generic novell probe 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 :-).

Eliminate the ED_VENDOR_{PCCARD,LINKSYS} types. These cards really are NOVELL NE2000 with just a tiny quirk that's non vendor specific. Instead, use the chip_type of DL100XX instead. This is more inline with how the AX88190 support was added, and seems a little cleaner.

Extricate probing of the gwether card (Gateway AT) from the middle of probing the novell ne[12]000 cards. It should be its own thing, ala how we do the dl100xx support doing its own thing at the right time. For the moment, it is just a function, which makes the mainline of the generic probe easier to follow. Also, correct a couple of comments that looked wrong. # there may be a bug in setting up gwether, in that we set # sc->rec_page_stop based on memsize, rather than sc->mem_size, so if # these two are different, then the rec_page_stop will be wrong. I'm # hesitant to fix it without real hardware to test with. Since # gwether isn't in the hardware list of the man page nor in the commit # messages, it is hard to know for sure.

Move the harvesting of the MAC address out of the generic novell probe 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 :-).

* Most ne1000/ne2000 compatible cards have their MAC address
* located in the first few words of the address space. This seems
* universally true for ISA and PCI implementations, but PC Card
* devices seem to have more variance.

Stop embedding struct ifnet at the top of driver softcs. Instead the 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.
