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.

Create mediachg functions for the 3c503 and hpp cards. This is used to properly configure the right interface to use. Also call the mediachg function when we set flags UP and are already running. If this were a pure ifmedia driver, we'd not need to do this since we'd be ignoring the linkX flags. This reduces the number of ifdefs to support sub-devices a little as a nice side effect. It also reduces the number of hpp interfaces exposed by 33%.

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.

If this were a pure ifmedia driver, we'd not need to do this since we'd be ignoring the linkX flags. This reduces the number of ifdefs to support sub-devices a little as a nice side effect. It also reduces the number of hpp interfaces exposed by 33%.

Have a function pointer to the routine to call for writing an mbuf into the card's memory. # this eliminates a more of the ifdef soup in if_ed and if_edvar # I've fixed the cbus drivers, but can't test them all easily. If I've broken anything, please let me know.

Create mediachg functions for the 3c503 and hpp cards. This is used to properly configure the right interface to use. Also call the mediachg function when we set flags UP and are already running.

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.
