- Rip out all the static softc stuff and do softc allocation the right way. - Rewrite most of the ISA code so that it provides a DEVICE_IDENTIFY method to enumerate all non-PnP ISA devices. This has the following consequences: - No 'ep' devices may be hardwired. - All hardwired devices will probably be detected twice. By hardwired I mean: device ep0 at isa? port 0x300 irq 10 - 'ep' devices are ordered by bus, slot, and then MAC address. - Make 3c509B cards work in PnP mode. Yes, they really work. - Convert over to using ifmedia for media selection. No more of this lame 'linkX' stuff. - Consolidate a lot of duplicated code. - Make a stab at not breaking MII based PCCARD devices. I doubt that the PCCARD stuff works any more than it did before my changes but theres hope. My PCCARD hardware should arrive in a week or so. - Retreive the media settings from the card EEPROM rather than guessing. I've got a 3c509-TPO that thinks its got an AUI port and if others can report similar problems I'll write a bit of clever code that will fix this but right now it works correctly on all but 1 card. - Clean up a few things and make some cosmetic changes. - Add myself as the MAINTAINER since nobody else wants to. I'm in the best position to do this as I've got an example of most of the cards: EISA 3c579 bnc/aui MCA 3c529 tp/aui ISA 3c509 tpo ISA-PnP 3c509B combo If someone wants to send me a any cards I don't have I'd appriciate it. Also welcome are 3c59x boards since I'll be folding if_vx and if_ep at some point.
