I repeatedly get __stack_chk_fail panic()s with this driver before
applying the attached fix.
ieee80211_wx_get_name() ignores sizeof(wrqu->name) which is IFNAMSIZ (16), and
on certain conditions, the concatenated string will be larger than IFNAMSIZ
including the terminating zero.
length ("802.11" ++ "b" ++ "/g" ++ " linked" ++ "\x00") == 17
This fix uses strl{cpy,cat} in addition to the reduction of the total
possible length of the output string by a char.
It can be applied to 2.6.30-stable as well.
