attached and ifconfigable. The card doesn't interrupt yet. Also, move towards bus space by introducing new macros/inline functions which make such a move much easier than before. These inline functions are setup now to work around an IBM EtherJet pccard cardbus bridge incompatibility. The card works in 8 bit mode, but not in 16-bit mode when it is connected to a cardbus bridge for reasons unknown. The Linux driver also has a similar workaround in it. Future work will include making the above workaround runtime conditional rather than compile time conditional, as well as fixing the interrupts in pccards and converting it to bus space.
