Either by upgrading to a kernel version that includes WE-18
(wireless-2.6 tree snapshot or wait for the next release) or by patching
your current kernel with the patch from

Actually, mode and probe_delay were removed from WE-18. Anyway, the
current Host AP driver snapshot supports SSID selection for the scan
(i.e., essid_len and essid from this list). 0.3.7 release allows SSID
parameter, but its WE-18 support does not match completely with the
version of wireless extensions that went in the wireless-2.6 tree.
