Andrey Skvortsov 5580373fb2 SSB / B44: fix WOL for BCM4401
Wake On Lan was not working on laptop DELL Vostro 1500.
If WOL was turned on, BCM4401 was powered up in suspend mode. LEDs blinked.
But the laptop could not be woken up with the Magic Packet. The reason for
that was that PCIE was not enabled as a system wakeup source and
therefore the host PCI bridge was not powered up in suspend mode.
PCIE was not enabled in suspend by PM because no child devices were
registered as wakeup source during suspend process.
On laptop BCM4401 is connected through the SSB bus, that is connected to the
PCI-Express bus. SSB and B44 did not use standard PM wakeup functions
and did not forward wakeup settings to their parents.
To fix that B44 driver enables PM wakeup and registers new wakeup source
using device_set_wakeup_enable(). Wakeup is automatically reported to the parent SSB
bus via power.wakeup_path. SSB bus enables wakeup for the parent PCI bridge, if there is any
child devices with enabled wakeup functionality. All other steps are
done by PM core code.

drivers to work better with rate control even if they don't have perfect

one of the regulatory patches from Arik, and a number of cleanups and

Of note is a patch where I disable CFG80211_WEXT so that compatibility
is no longer selectable - this is intended as a wake-up call for anyone
who's still using it, and is still easily worked around (it's a one-line
patch) before we fully remove the code as well in the future."

Christophe Ricard a2ae218298 NFC: hci: Add support for NOTIFY_ALL_PIPE_CLEARED
When switching from UICC to another, the CLF may signals to the Terminal
Host that some existing pipe are cleared for future update.

This notification needs to be "acked" by the Terminal Host with a ANY_OK
message.

Christophe Ricard deff5aa469 NFC: hci: Add open pipe command handler
If our terminal connect with other host like UICC, it may create
a pipe with us, the host controller will notify us new pipe
created, after that UICC will open that pipe, if we don't handle
that request, UICC may failed to continue initialize which may
lead to card emulation feature failed to work

Vladimir Kondratiev cce47711f3 wil6210: reset flow update
If card reset with firmware download executed, followed by reset
with use of firmware from build in flash, firmware download indication
remains in the hardware register.
When running firmware download flow,
the SW download indication is written by the driver to bit 0 in usage_6:
wil_fw_load(), "S(RGF_USER_USAGE_6, 1);"
This register, like all USER RGF, wasn't reset in SW reset flow.
Therefore the driver must clear it on SW reset flow.

Vladimir Kondratiev 70801e1b1e wil6210: Rate limit "ring full" error message
In the wil_tx_ring, error message printed when tx attempted
while vring has no space to accommodate all fragments of frame.
Normally, such situation handled by stopping tx queue.
But, if tx queue is by-passed (like pktgen does), this error
will be triggered at high rate and dmesg will be flooded with
this message. Whole system may become unstable and hang with
no possible recover except power cycle.

Rate-limit it to prevent dmesg flooding.
