mac80211: avoid "Wireless Event too big" message for assoc response
The association response IEs are sent to userland with an IWEVCUSTOM
event, which unfortunately is limited to a little more than 100 bytes
of IE information with the encoding used. Many APs send so much
IE information that this message overflows. When the IWEVCUSTOM
event is too large, the kernel doesn't send it to userland anyway --
better just not to send it.
An attempt was made by Jouni Malinen to correct this issue by
converting to use IWEVASSOCREQIE and IWEVASSOCRESPIE messages instead
("mac80211: Use IWEVASSOCREQIE instead of IWEVCUSTOM"). Unfortunately,
that caused a problem due to 32-/64-bit interactions on some systems and
was reverted after the 'userland ABI' rule was invoked. That leaves
us with this option instead of a proper fix, at least until we move
to a cfg80211-based solution.

DESCRIPTION
"The number of out of the blue packets received by the host.
An out of the blue packet is an SCTP packet correctly formed,
including the proper checksum, but for which the receiver was
unable to identify an appropriate association."
REFERENCE
"Section 8.4 in RFC2960 deals with the Out-Of-The-Blue
(OOTB) packet definition and procedures."
But OOTB packet INIT, INIT-ACK and SHUTDOWN-ACK(COOKIE-WAIT or
COOKIE-ECHOED state) are not counted by SCTP_MIB_OUTOFBLUES.
Case 1(INIT):
Endpoint A Endpoint B
(CLOSED) (CLOSED)
INIT ---------->
<---------- ABORT
Case 2(INIT-ACK):
Endpoint A Endpoint B
(CLOSED) (CLOSED)
INIT-ACK ---------->
<---------- ABORT
Case 3(SHUTDOWN-ACK):
Endpoint A Endpoint B
(CLOSED) (CLOSED)
<---------- INIT
SHUTDOWN-ACK ---------->
<---------- SHUTDOWN-COMPLETE
Case 4(SHUTDOWN-ACK):
Endpoint A Endpoint B
(CLOSED) (COOKIE-ECHOED)
SHUTDOWN-ACK ---------->
<---------- SHUTDOWN-COMPLETE
This patch fixed the problem.

sctp: Fix to start T5-shutdown-guard timer while enter SHUTDOWN-SENT state
RFC 4960: Section 9.2
The sender of the SHUTDOWN MAY also start an overall guard timer
'T5-shutdown-guard' to bound the overall time for the shutdown
sequence. At the expiration of this timer, the sender SHOULD abort
the association by sending an ABORT chunk. If the 'T5-shutdown-
guard' timer is used, it SHOULD be set to the recommended value of 5
times 'RTO.Max'.
The timer 'T5-shutdown-guard' is used to counter the overall time
for shutdown sequence, and it's start by the sender of the SHUTDOWN.
So timer 'T5-shutdown-guard' should be start when we send the first
SHUTDOWN chunk and enter the SHUTDOWN-SENT state, not start when we
receipt of the SHUTDOWN primitive and enter SHUTDOWN-PENDING state.
If 'T5-shutdown-guard' timer is start at SHUTDOWN-PENDING state, the
association may be ABORT while data is still transmitting.

sctp: try harder to figure out address family when checking wildcards
sctp_is_any() function that is used to check for wildcard addresses
only looks at the address itself to determine the address family.
This function is used in the API to check the address passed in from

rt2x00: Fix build errors due to modularized rfkill or leds and built-in rt2x00.
Fix by disabling rt2x00 rfkill support when rt2x00 is built-in and rfkill has been modularized, and
a similar scheme for the relationship between leds_class and rt2x00..
Also, give a warning to the end-user when rfkill-/leds-support is disabled this way, so that the
end-user has at least some clues on what is going on.
Proper fixing required some general updates of the Kconfig-structure for the rt2x00 driver, whereby

All of the above have been fixed. One question, however, remains: In struct
bootrec, the array "data" is treated in many places as native CPU order, but
it may be little-endian everywhere. As far as I can tell, this driver has only
been used with little-endian hardware.
