Bug 238657

wireless-tools-28-2.fc7
kernel-2.6.21-1.3116.fc7

After upgrading to the new wireless tools and NetworkManager in today's rawhide,
ipw3945 on x86_64 stopped working.  I don't see any signs on the surface of what
went wrong, except this segfault:

Starting program: /sbin/iwlist eth0 scan
Warning: Driver for device eth0 has been compiled with version 22
of Wireless Extension, while this program supports up to version 20.
Some things may be broken...
