2a3c2a37f6 Change the MLME ASSOCIATE ioctl to accept either a ssid, a bssid, 
or a bssid+ssid. This is needed for later versions of wpa_supplicant
and for forthcoming addons to wpa_supplicant.

Note this is an api change and applications must be rebuilt.

8ace9dabca Revise crypto api lightly to improve group key handling: 
o don't pre-assign key index to the global key table entries so device
  has a chance to decide what to use
o make ieee80211_crypto_newkey take the desired flags as an argument
  instead of wacking the key structure directly; this eliminates a
  bunch of code warts
o add a new flag IEEE80211_KEY_GROUP to indicate a key is a WPA Group
  key so devices don't need to guess (temporarily add this flag in the
  ioctl code until we can get wpa_supplicant+hostapd updated)
o shuffle IEEE80211_KEY_* bits to move flags used internally to the high
  nibble of the flags word

8afa2c4c26 Recently, it was reported to me that you could provoke a double fault 
panic with the NDISulator if you did "ifconfig ndis0 10.0.0.1/24,"
whereas "ifconfig ndis0 10.0.0.1/24 up" worked fine. The double fault
was caused by the ifconfig thread running out of kernel stack space.
(This was partly due to the NDIsulator using a couple of big buffers on
the stack, but even after fixing that the double fault persisted.)

It turns out that ndis_init() is called in both cases, but in the first
case the code path passes through ieee80211_ioctl(), and it turns out
ieee80211_ioctl() consumes a whopping 2400 bytes of stack space.
Apparently, gcc -O2 causes the ieee80211_ioctl_get80211() routine to
be inlined into ieee80211_ioctl(), and for some reason which I do not
fully understand, this causes ieee80211_ioctl() to consume an extra 2K
of stack space.

To prevent this overly agressive optimization, ieee80211_ioctl_get80211()
is now declared with __attribute__ ((noinline)). With this change,
ieee80211_ioctl() now only reserves about 200 bytes of stack instead of 2400.

ae59d17866 Explicitly ignore ibss merge requests when the node is ic_bss. This can 
happen on the first management frame received from a neighbor; we assume
any merge candidate will send more frames and those should be processed
with a suitable table entry.
