Severity: important


Running iwconfig with no arguments results in a segfault under Sparc.
I've tried different kernels, and different drivers (orinoco_pci,
linux_wlan_pci, currently hostap_pci), and the results are always the
same. Type script follows (wireless interface is wlan0):

[email protected]:~# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.
