The expected throughput table used when estimating a new column
depends on the channel bandwidth. When switching from legacy to
siso or mimo the wrong expected throughput table was used as it
was chosen based on the the channel bandwidth in legacy which is
always 20Mhz. Instead it should be chosen based on the current sta
bandwidth which could be also 40Mhz or 80Mhz.
When enabling MCS9 this bug leads to a problem where the max
expected throughput of the siso or mimo column is 0 as MCS9 isn't
supported in 20Mhz. This in turns prevents switching to siso or mimo.
Fix this by using the sta bandwidth when deciding which table to choose.

Under "heavy" RX load, the driver cannot handle the descriptors fast
enough. In detail, when a descriptor is consumed, its used flag is
cleared and once the RX budget is consumed all descriptors with a
cleared used flag are prepared to receive more data. Under load though,
the HW may constantly receive more data and use those descriptors with a
cleared used flag before they are actually prepared for next usage.
The head and tail pointers into the RX-ring should always be valid and
we can omit clearing and checking of the used flag.

Intel Wired LAN Driver Updates
This series contains updates to e1000e only.
David provides four fixes for e1000e, first is a workaround for a hardware
erratum on 82579 devices which experienced packet loss in gigabit and 100
speeds when interconnect between the PHY and MAC is exiting K1 power saving
state. Second expands the scope of a workaround to include i217 and i218
parts as well to address over aggressive transmit behavior when connecting
at 10Mbs half-duplex. Next is to resolve a reported link flap issue on
82579 parts which was root caused as an interoperability problem between
82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake
mechanism. Lastly, restricts the workaround of putting the PHY into MDIO
slow mode to access the PHY id to relevant parts since this issue has been
fixed on the newer hardware.

It has been determined that the workaround of putting the PHY into MDIO
slow mode to access the PHY id is not necessary with Lynx Point and newer
parts. The issue that necessitated the workaround has been fixed on the
newer hardware.
We will maintains, as a last ditch attempt, the conversion to MDIO Slow
Mode in the failure branch when attempting to access the PHY id so as to
cover all contingencies.

Several customers have reported a link flap issue on 82579. The symptoms
are random and intermittent link losses when 82579 is connected to specific
link partners. Issue has been root caused as interoperability problem
between 82579 and at least some Broadcom PHYs in the Energy Efficient
Ethernet wake mechanism.
To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
Low Power Idle. This solution will cause an increase of power in 100M EEE
link. It will cost additional 28mW in this specific mode.

This is a workaround for a HW erratum on 82579 devices.
Erratum is #23 in Intel 6 Series Chipset and Intel C200 Series Chipset
specification Update June 2013.
Problem: 82579 parts experience packet loss in Gig and 100 speeds
when interconnect between PHY and MAC is exiting K1 power saving state.
This was previously believed to only affect 1Gig speed, but has been observed
at 100Mbs also.
Workaround: Disable K1 for 82579 devices at Gig and 100 speeds.

This introduces another flag in 'quirks' to replace the preprocessor
define (USE_MMIO) used to indicate whether the device needs a
separate enable routine to operate in MMIO mode.
All of the currently known platform Rhine cores operate in MMIO
mode by default, and on PCI it is preferred over PIO for performance
reasons. However, a comment in code suggests that some (?) early
Rhine cores only work in PIO mode, so they should not be switched
to MMIO.
Enabling MMIO on PCI is still triggered by the same Kconfig option
to avoid breaking user configs needlessly, but this can be changed
going forward towards automatic runtime detection in case a list of
PIO-only Rhine revisions can be compiled.
This also fixes a couple of compiler warnings detected by Fengguang
Wu's test bot (!USE_MMIO case):

Commit 4d619f625a60 ("net: cdc_ncm: no point in filling up the NTBs
if we send ZLPs") changed the padding logic for devices with the ZLP
flag set. This meant that frames of any size will be sent without
additional padding, except for the single byte added if the size is
a multiple of the USB packet size. But if the unpadded size is
identical to the maximum frame size, and the maximum size is a
multiplum of the USB packet size, then this one-byte padding will
overflow the buffer.
Prevent padding if already at maximum frame size, letting usbnet
transmit a ZLP instead in this case.

In ath10k we had more changes, major ones being:
* fix memory allocation failures after a firmware crash (Michal)
* some rework of DFS configuration to enable it correctly in all cases
(Michal)
* add a new firmware crash option to make it possible to crash 10.1
firmware for testing purposes (Marek P)
* fix RTS/CTS protection in certain cases (Marek K)
* fix wrong RSSI and rate reporting in some cases (Janusz)
* fix firmware stats reporting (Chun, Ben & Bartosz)"
For the iwlwifi bits, Emmanuel says:
"I have here a bunch of unrelated things. I disabled support for
-7.ucode which means that I can removed a lot of code. Eliad has
a brand new feature: we reduce the Tx power when the link allows -
this reduces our power consumption. The regular changes in power and
scan area. One interesting thing though is the patches from Johannes,
we have now GRO which allows to increase our throughput in TCP Rx. The
main advantage is that it reduces the number of TCP Acks - these TCP
Acks are completely useless when we are using A-MPDU since the first
packet of the A-MPDU generates a TCP Ack which is made obsolete by
the next packets."
Along with that, there are a variety of updates to b43, mwifiex,
rtl8180 and wil6210 drivers and a handful of other updates here
and there.
Please let me know if there are problems!
