description:
Ipf is initalized in vap_setup, so don't initialize twice.

Don't overload variables set in vap/setup attach.  The exeption being the dev
name for now.

Scan improvements for urtwn from iwn, always force a full scan.

Only call ieee80211_init from device specific init as this is what is
used in the ifp structure.
