Add support for VSOL V2801F/CarlitoxxPro CPGOS03 GPON module
This patch set adds support for the V2801F / CarlitoxxPro module. This
requires two changes:
1) the module only supports single byte reads to the ID EEPROM,
while we need to still permit sequential reads to the diagnostics
EEPROM for atomicity reasons.
2) we need to relax the encoding check when we have no reported
capabilities to allow 1000base-X based on the module bitrate.
Thanks to Pali Rohár for responsive testing over the last two days.

Do not check the encoding when deriving 1000BASE-X from the bitrate
when no other modes are discovered. Some GPON modules (VSOL V2801F
and CarlitoxxPro CPGOS03-0490 v2.0) indicate NRZ encoding with a
1200Mbaud bitrate, but should be driven with 1000BASE-X on the host
side.

need to handle the Restart Request received, rather than ignore it.
2. When we are in X25_LINK_STATE_2, we have already sent a Restart Request
and is waiting for the Restart Confirmation with t20timer. t20timer will
restart itself repeatedly forever so it will always be there, as long as we
are in State 2. So we don't need to check x25_t20timer_pending again.

When the workqueue disposes of the msk, the subflows can still
receive some data from the peer after __mptcp_close_ssk()
completes.
The above could trigger a race between the msk receive path and the
msk destruction. Acquiring the mptcp_data_lock() in __mptcp_destroy_sock()
will not save the day: the rx path could be reached even after msk
destruction completes.
Instead use the subflow 'disposable' flag to prevent entering
the msk receive path after __mptcp_close_ssk().

When a MPTCP listener socket is closed with unaccepted
children pending, the ULP release callback will be invoked,
but nobody will call into __mptcp_close_ssk() on the
corresponding subflow.
As a consequence, at ULP release time, the 'disposable' flag
will be cleared and the subflow context memory will be leaked.
This change addresses the issue always freeing the context if
the subflow is still in the accept queue at ULP release time.
Additionally, this fixes an incorrect code reference in the
related comment.
Note: this fix leverages the changes introduced by the previous
commit.

After commit 0397c6d85f ("mptcp: keep unaccepted MPC subflow into
join list"), the msk's workqueue and/or PM can touch the MPC
subflow - and acquire its socket lock - even if it's still unaccepted.
If the above event races with the relevant listener socket close, we
can end-up with the above splat.
This change addresses the issue delaying the MPC socket insertion
in conn_list at accept time - that is, partially reverting the
blamed commit.
We must additionally ensure that mptcp_pm_fully_established()
happens after accept() time, or the PM will not be able to
handle properly such event - conn_list could be empty otherwise.
In the receive path, we check the subflow list node to ensure
it is out of the listener queue. Be sure client subflows do
not match transiently such condition moving them into the join
list earlier at creation time.
Since we now have multiple mptcp_pm_fully_established() call sites
from different code-paths, said helper can now race with itself.
Use an additional PM status bit to avoid multiple notifications.

mptcp: Add port parameter to ADD_ADDR option
The ADD_ADDR MPTCP option is used to announce available IP addresses
that a peer may connect to when adding more TCP subflows to an existing
MPTCP connection. There is an optional port number field in that
ADD_ADDR header, and this patch set adds capability for that port number
to be sent and received.
Patches 1, 2, and 4 refactor existing ADD_ADDR code to simplify implementation
of port number support.
Patches 3 and 5 are the main functional changes, for sending and
receiving the port number in the MPTCP ADD_ADDR option.
Patch 6 sends the ADD_ADDR option with port number on a bare TCP ACK,
since the extra length of the option may run in to cases where
sufficient TCP option space is not available on a data packet.
Patch 7 plumbs in port number support for the in-kernel MPTCP path
manager.
Patches 8-11 add some optional debug output and a little more cleanup
refactoring.

Change interrupt trigger from IRQ_TYPE_LEVEL_HIGH to IRQ_TYPE_EDGE_RISING
for stable NFC I2C interrupt handling.
Samsung's NFC Firmware sends an i2c frame as below.
1. NFC Firmware sets the GPIO(interrupt pin) high when there is an i2c
frame to send.
2. If the CPU's I2C master has received the i2c frame, NFC F/W sets the
GPIO low.
NFC driver's i2c interrupt handler would be called in the abnormal case
as the NFC FW task of number 2 is delayed because of other high priority
tasks.
In that case, NFC driver will try to receive the i2c frame but there isn't
any i2c frame to send in NFC.
It would cause an I2C communication problem. This case would hardly happen.
But, I changed the interrupt as a defense code.
If Driver uses the TRIGGER_RISING instead of the LEVEL trigger,
there would be no problem even if the NFC FW task is delayed.

This patchset by Moshe contains fixes to the mlx4 Eth driver,
addressing issues in restart flow.
Patch 1 protects the restart task from being rescheduled while active.
Please queue for -stable >= v2.6.
Patch 2 reconstructs SQs stuck in error state, and adds prints for improved
debuggability.
Please queue for -stable >= v3.12.

In case error CQE was found while polling TX CQ, the QP is in error
state and all posted WQEs will generate error CQEs without any data
transmitted. Fix it by reopening the channels, via same method used for
TX timeout handling.
In addition add some more info on error CQE and WQE for debug.

Add restarting state flag to avoid scheduling another restart task while
such task is already running. Change task name from watchdog_task to
restart_task to better fit the task role.
