My Aironet 350 PCMCIA card also shows up as both eth1 and wifi0, but for
use _on a network_ I configure it as eth1.  According to
http://cvs.sourceforge.net/viewcvs.py/airo-linux/airo-linux/kernel/airo.c,
the purpose of "wifi0" is "to allow transmission and reception (in RFMon)
of raw 802.11 frames", that is, wifiM and ethN have completely different
purposes.  (The hostap driver for Prism2 cards also seems to have this
arrangement, although there the cooked interface is called "wlanM".)

I believe that wireless 802.11* is an Ethernet variant, even though no
wires are involved.  Anyway, as recently argued over there in debian-devel
(http://lists.debian.org/debian-devel/2005/02/msg00343.html), many (most?
all?) of the wireless interfaces in the mainline Linux kernel are called
ethM (orinoco, aironet, prism54, ...).

I tried to allude to this in my previous post
