Patch fixes the bug at
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903
when SW rfkill is invoked by 'iwconfig txpower off',
the existing connection disassociates and led off command is sent
to the device which returns error as rfkill is 'true'.
Patch fixes this by just avoiding sending the led off/on command when
disassociated. The main purpose of the led_disassociate callback
is to start or stop the blinking.
There are three states in led
1) Always on when radio is on
2) Always off when radio is off
3) blink when associated and if there is some traffic.
In this callback 'allow_blinking' needs to be set false
when associated, as LED will be always on.

rfkill: create useful userspace interface
The new code added by this patch will make rfkill create
a misc character device /dev/rfkill that userspace can use
to control rfkill soft blocks and get status of devices as
well as events when the status changes.
Using it is very simple -- when you open it you can read
a number of times to get the initial state, and every
further read blocks (you can poll) on getting the next
event from the kernel. The same structure you read is
also used when writing to it to change the soft block of
a given device, all devices of a given type, or all
devices.
This also makes CONFIG_RFKILL_INPUT selectable again in
order to be able to test without it present since its
functionality can now be replaced by userspace entirely
and distros and users may not want the input part of
rfkill interfering with their userspace code. We will
also write a userspace daemon to handle all that and
consequently add the input code to the feature removal
schedule.
In order to have rfkilld support both kernels with and
without CONFIG_RFKILL_INPUT (or new kernels after its
eventual removal) we also add an ioctl (that only exists
if rfkill-input is present) to disable rfkill-input.
It is not very efficient, but at least gives the correct
behaviour in all cases.

The comment (which I remove) says that the translation is done SPI routines.
IMHO this can't work because the SPI driver does not know whether the incomming
bytes are part of the registers/bytes which need to be flipped or part of
packet data which has to remain untouched.
While adding le helpers I also removed spu_write_u32() which has no users.

sctp: support non-blocking version of the new sctp_connectx() API
Prior implementation of the new sctp_connectx() call that returns
an association ID did not work correctly on non-blocking socket.
This is because we could not return both a EINPROGRESS error and
an association id. This is a new implementation that supports this.

B4) Re-transmit the ASCONF Chunk last sent and if possible choose an
alternate destination address (please refer to [RFC4960],
Section 6.4.1). An endpoint MUST NOT add new parameters to this
chunk; it MUST be the same (including its Sequence Number) as
the last ASCONF sent. An endpoint MAY, however, bundle an
additional ASCONF with new ASCONF parameters with the next
Sequence Number. For details, see Section 5.5.
This patch fix to choose an alternate destination address when
re-transmit the ASCONF chunk, with some dup codes cleanup.
sctp: fix panic when T4-rto timer expire on removed transport
If T4-rto timer is expired on a removed transport, kernel panic
will occur when we do failure management on that transport.
You can reproduce this use the following sequence:
sctp: fix panic when T2-shutdown timer expire on removed transport
If T2-shutdown timer is expired on a removed transport, kernel
panic will occur when we do failure management on that transport.
You can reproduce this use the following sequence:
Endpoint A Endpoint B
(ESTABLISHED) (ESTABLISHED)
<----------------- SHUTDOWN
(SRC=X)
ASCONF ----------------->
(Delete IP Address = X)
<----------------- ASCONF-ACK
(Success Indication)
<----------------- SHUTDOWN
(T2-shutdown timer expire)
This patch fixed the problem.
sctp: fix the error code when ASCONF is received with invalid address
Use Unresolvable Address error cause instead of Invalid Mandatory
Parameter error cause when process ASCONF chunk with invalid address
since address parameters are not mandatory in the ASCONF chunk.
sctp: fix report unrecognized parameter in ACSONF-ACK
RFC5061 Section 5.2. Upon Reception of an ASCONF Chunk
V2) In processing the chunk, the receiver should build a
response message with the appropriate error TLVs, as
specified in the Parameter type bits, for any ASCONF
Parameter it does not understand. To indicate an
unrecognized parameter, Cause Type 8 should be used as
defined in the ERROR in Section 3.3.10.8, [RFC4960]. The
endpoint may also use the response to carry rejections for
other reasons, such as resource shortages, etc., using the
Error Cause TLV and an appropriate error condition.
So we should indicate an unrecognized parameter with error
SCTP_ERROR_UNKNOWN_PARAM in ACSONF-ACK chunk, not
SCTP_ERROR_INV_PARAM.
RFC5061 had changed the error cause codes for Dynamic Address
Reconfiguration As the following:
Cause Code
Value Cause Code
--------- ----------------
0x00A0 Request to Delete Last Remaining IP Address
0x00A1 Operation Refused Due to Resource Shortage
0x00A2 Request to Delete Source IP Address
0x00A3 Association Aborted Due to Illegal ASCONF-ACK
0x00A4 Request Refused - No Authorization

fsl_pq_mido: Set the first UCC as the mii management interface master
Current code makes the UCC whose register range includes the current mdio
register to be the MII managemnt interface master of the QE. If there is more
than one mdio bus for QE, the UCC of the last mdio bus will be the MII
management interface master which will make the primary mdio bus working
unproperly, e.g. can not get the right clock. Normally the primary mdio bus is
the first UEC's mdio bus.
This patch allows the first UCC to be the MII management interface master of the
multiple UCC mdio buses.
