This is a bug revealed in r41830.
First, the static variable `char nif[IFNAMSIZ]` of nl80211_phy2ifname()
would be zeroed out if the argument is "wlan0" or the like. This will
happen in the following call stack.
nl80211_get_scanlist("radio0", buf, len);
nl80211_phy2ifname("radio0") // return static var nif with content "wlan0"
nl80211_get_scanlist(nif, buf, len); // tail call
nl80211_get_mode(nif);
nl80211_phy2ifname(nif); // zero out nif
Later we try nl80211_ifadd("") which was supposed to create interface
"tmp.", but that won't happen because nl80211_msg() will put an invalid
ifidx 0 to the nlmsg.
Then iwinfo_ifup() and iwinfo_ifdown() would fail and happily
nl80211_get_scanlist() returned 0 and left *len undefined.

If the iface to scan on already is in ad-hoc, station or monitor mode
then do not spawn a temporary iface.
Also preventively disable IPv6 on temporary ifaces before bringing them
up to avoid potential security issues.

So far iwinfo aborted a wifi scan attempt if the mac of the spawned
interface could not be changed. Change the code to try anyway - this
should fix wifi scanning on RaLink devices.

The associations list for Broadcom WDS interfaces are duplicate to those
reported by the corresponding AP interface; so there is no need to report
them again.

Modify the hwmodelist reporting for broadcom devices to include
proper reporting of 802.11n support.

There are several cases within 'luci' that attempt to access the interface
'type' from within the 'type' specific meta tables; however, 'type' is not
currently available there. Replicate the common metadata in the 'type'
specific meta tables.

wpa_supplicant may send log and event messages intermixed with the
expected scan results. This makes "iwinfo wlan0 scan" and LuCI
"site survey" display nothing when many AP's are around.
Eliminate the CTRL-EVENT-BSS-ADDED events, interspersed log messages,
lines with unexpected format. Increase timeout to handle the max
number of channels (2.4, 3.6, 4.9, 5 GHz). Insure receive buffer is
null-terminated.
