From what I've read, the vortex cards do resemble the older Etherlink
IIIs, so yes those two could probably be merged. However, the 3c900+
cards have a true bus mastering PCI architecture, so it makes sense to fit
them into a seperate driver, such as if_xl.
I guess they could be merged, but it would mostly be a mess.
Here's another thing I'm confused about:
from if_xlreg.h:
#define TC_DEVICEID_HURRICANE_556 0x6055
from if_ep_pccard.c:
case 0x6055: /* 3C556 */
Is it possible that 3Com used the same chip in mini-pci and pccard
designs? This does seem possible, as 3c905 (pre-B, I don't know about the
mini-PCI version) cards support the 3c509 interface.
