They are merged in NetBSD. I think Matt Dodd has some patches that do
this.

Just because it is true bus mastering doesn't mean that it makes sense
to have a different driver... I haven't looked at the structure of
these two drivers to know if this makes sense or not. I was mostly
speculating out loud...

: #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.
Likely just a compat thing. The 3com interfaces seem to have lots
backward compat stuff (did you know you can get the EISA id out of
pcmcia devices, at least the 3c1?)
