John W. Linville says:
====================
Here is one last(?) big wireless bits pull request before the merge window...
Regarding the mac80211 bits, Johannes says:
"Here's another big pull request for the -next stream. This one has a ton
of driver updates, which hopefully addresses all drivers, but maybe you
have more new drivers than I have in my tree? Not entirely sure, let me
know if this is the case and then I can merge wireless-next.
I'm including a large number of small changes, see the shortlog. The two
bigger things are making VHT compatible with not using channel contexts
(from Karl) and the stop-while-suspended fixes I developed together with
Stanislaw."
...and...
"This time I have a relatively large number of fixes and small
improvements, the most important one being Bob's RCU fix. The two big
things are Felix's work on rate scaling tables (with a big thanks to
Karl too) and my own work on CSA handling to finally properly handle HT
(and some VHT.)"
As for the iwlwifi bits, Johannes says:
"The biggest work here is Bluetooth coexistence and power saving. Other
than that, I have a few small fixes that weren't really needed for 3.9
and a new PCI ID."
About the NFC bits, Samuel says:
"With this one we have:
- A major pn533 update. The pn533 framing support has been changed in order to
easily support all pn533 derivatives. For example we now support the ACR122
USB dongle.
- An NFC MEI physical layer code factorization through the mei_phy NFC API.
Both the microread and the pn544 drivers now use it.
- LLCP aggregation support. This allows NFC p2p devices to send aggregated
frames containing all sort of LLCP frames except SYMM and aggregation
frames.
- More LLCP socket options for getting the remote device link parameters.
- Fixes for the LLCP socket option code added with the first pull request for
3.10.
- Some support for LLCP corner cases like 0 length SDUs and general DISC
(tagged with a 0,0 dsap ssap couple) handling.
- RFKILL support for NFC."
For the b43 bits, Rafał says:
"Let me remind the changes for b43:
> Changes include:
> 1) Minor improvements for HT-PHY code (BCM4331)
> 2) Code cleaning for HT-PHY and N-PHY"
Concerning the bluetooth bits, Gustavo says:
"A set of changes intended for 3.10. The biggest changes here are from David
Herrmann, he rewrote most of the HIDP layer making it more reliable. Marcel
added a driver setup stage for device that need special handling on their
early initialization. Other than that we have the usual clean ups, bugfixes
and small improvements."
Along with all that, there is the usual collection of random/various
updates to ath9k, mwifiex, brcmfmac, brcmsmac, rt2x00, and wil6210.
I also included a pull of the wireless tree to resolve a merge conflict.
Please let me know if there are problems!

Depending of the kernel configuration (CONFIG_UIDGID_STRICT_TYPE_CHECKS), we can
get the following errors:

Rotate bss prio list, so the bss next to the one served, will come first
in the list of bss' with equal priority. This way we pick bss nodes in a
round robin fashion. Using list rotation instead of a cur ptr simplifies
iteration to calling list_for_each_entry. List rotation is done via
list_move, where the head itself is temporarily removed and then
re-inserted after the bss just served.

After a packet is successfully transmitted, ra list is rotated, so the ra
next to the one transmitted, will be the first in the list. This way we
pick the ra' in a round robin fashion. This significantly simplifies
iteration in mwifiex_wmm_get_highest_priolist_ptr to a call to
list_for_each_entry.

The firmware provides credits to the driver per WMM-AC. When
only AC_BE are to be transmitted to the firmware the driver
may use credits from other priorities to send AC_BE packets
towards the firmware.

In brcmf_fws_init() the error flows were not properly handled
and the caller ignored the return value. The only action that
is allowed to fail in brcmf_fws_init() is setting the tlv in
firmware as the feature is not supported on all devices.

The RX fifo can be accessed from the common tasklet or it can
be reaped/cleaned when RX is stopped, which is done when doing
a reset or channel change - this happens in process context.
Since it is ensured that there are no pending tasklets when
stopping RX and cleaning the FIFO, there is no need to use
SKB queue functions which take internal locks.

In MMIO dumps of ndiswrapper there are following PHY ops:
phy_read(0x0118) -> 0x013d
phy_read(0x01ed) -> 0x993d
phy_read(0x0119) -> 0x012f
phy_read(0x01ee) -> 0x992f
phy_read(0x011a) -> 0x0139
phy_read(0x0969) -> 0x9939
It matches the code of wlc_phy_txpower_est_power_nphy (from brcm80211),

After comparing writes to registers at 0x000, 0x400 and 0x800 it seems

batadv_mesh_free() schedules some RCU callbacks which need the bat_priv struct

Put an rcu_barrier() in the middle so that free_netdev() is invoked only after
all the callbacks returned.
