Jeff Kirsher says:
====================
This series contains updates to ixgbe, igb and pci.
The ixgbe changes contains a fix to a possible divide by zero by bailing
out of the ixgbe_update_itr() function if the last interrupt timeslice is
zero. In addition, support is added for the new OCP x520 adapter as well
as LX support for 82599 devices. Jacob provides a patch to change
variable wol_supported to wol_enabled to better reflect what the code
is actually doing (i.e. checking if WoL is enabled).
Alex adds SRIOV helper function to pci that will determine if a PF
has any VFs that are currently assigned to a guest.
The remaining 8 patches are against igb and contain the following changes:
* implement SERDES loopback configuration for i210 devices by unsetting
sigdetect bit, so as to fix Ethtool loopback test failure
* add support for the SMBI semaphore for I210/I211 devices
* implement the new generic pci_vfs_assigned helper function (Alex's PCI
helper function)
* display warning when link speed is downgraded due to Smartspeed
* ensure that VLAN hardware filtering remains enabled when the device is
in promiscuous mode and VT mode simultaneously
* cleanup dead code in igb
* bump the driver version
v2: updated the PCI patch to add SRIOV helper function to remove extern
from the declaration of pci_vfs_assigned in pci.h and return 0 if
SR-IOV is disabled which is inline with other PCI SR-IOV functions

This patch introduces a more robust error handling flow in case of incorrect
behaviour by the FW when passing on GRO aggregations.
Although this should never happen (i.e., this is merely a theoretical fix),
if the bnx2x driver was to receive a GRO from FW with protocol other than
IPv4/IPv6, the driver would falsely claim to have performed partial
checksum and set various incorrect fields in the skb header.
Current behaviour of the bnx2x driver (i.e., print an error) is insufficient.

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.

According to 802.11-2007 17.3.8.6 (slot time), the slot time should
be increased by 3 us * coverage class. The code only increased the
ack timeout, which is fixed by this patch.
We have noticed in our long shot scenario that we see less collisions
with this patch.

b43: HT-PHY: define regs for power estimation
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),
so we know the registers meaning.

After comparing writes to registers at 0x000, 0x400 and 0x800 it seems
there are many very similar writes. So 0x000 offset is not for accessing
something totally different, but probably just the first out of three

ipvs: Use network byte order for sync message size
struct ip_vs_sync_mesg and ip_vs_sync_mesg_v0 are both sent across the wire
and used internally to store IPVS synchronisation messages.
Up until now the scheme used has been to convert the size field
to network byte order before sending a message on the wire and
convert it to host byte order when sending a message.
This patch changes that scheme to always treat the field
as being network byte order. This seems appropriate as
the structure is sent across the wire. And by consistently
treating the field has network byte order it is now possible
to take advantage of sparse to flag any future miss-use.

ipvs: Use min3() in ip_vs_dbg_callid()
There are two motivations for this:
1. It improves readability to my eyes
2. Using nested min() calls results in a shadowed _min1 variable,
which is a bit untidy. Sparse complained about this.
I have also replaced (size_t)64 with a variable of type size_t and value 64.
This also improves readability to my eyes.
