810659a22c ag71xx: Move timestamp struct member outside of struct.
With this change, the timestamp variable is only used in ag71xx_check_dma_stuck. Small tx speedup.

Based on a Qualcomm commit. ag->timestamp = jiffies was not replaced with netif_trans_update(dev) because of this quote:

It should be noted that after this series several instances
of netif_trans_update() are useless (if they occur in
.ndo_start_xmit and driver doesn't set LLTX flag -- stack already
did an update).

4e03a742e0 ag71xx: Reorder ag71xx struct members for better cache performance
Qualcomm claims this improves the D-cache footprint. Origina commit message below:

Subject: [ag71xx] cluster/align structs for cache perf

Cluster the frequently used, per-packet structures in ag71xx near
to each other, and cacheline-align them.  Some other re-ordering
occurred to move "warmer" structures near the per-packet structures.

8f44c8086b ar71xx: remove obsolete '< KERNEL_VERSION(4, 2, 0)' check
Because the oldest supported kernel version on the ar71xx target is 4.4,
the condition that the kernel version is smaller than 4.2.0 is always
false. Remove the obsolete check from ag71xx_main.c to clean up the code

6456999731 ar71xx: spi-rb4xx: balance clk_prepare_enable() call
Commit c312cef223 ("ar71xx: spi-rb4xx fix.") replaced the clk_enable() call
with clk_prepare_enable() to meet the common clock framework requirements.
However it did not change the clk_disable() call in the error patch which
thus leads to imbalance.

Fix the code by using the correct counterpart of clk_prepare_enable() in both
places.

Subject: [ag71xx] reduce NAPI weight

In an attempt to increase our cache warmth, we are decreasing NAPI.
This increases the warmth of the reused SKBs.

7bbf4117c6 ar71xx: Add kernel 4.9 support
This add support for kernel 4.9 to the ar71xx target.
It was compile tested with the generic, NAND and mikrotik subtarget.
Multiple members of the community tested it on their boards and did not
report any major problem so far.

Especially the NAND part received some changes to adapt to the new
kernel APIs. The serial driver hack used for the Arduino Yun was not
ported because the kernel changed there a lot.

224e5f5efa ar71xx: Add support for Teltonika RUT900
Teltonika RUT900 is a Router with LTE dual SIM, WiFi, 4x Ethernet
ports, I/O, RS232, RS485, GPS.

The device ist based on a Atheros AR9344 rev 3,

Specifications:
- 560/450/225 MHz (CPU/DDR/AHB)
- 128 MB of RAM
- 16 MB of FLASH
- Serial Console header on a Card Board edge connector
- 4x 10/100 Mbps Ethernet (3x LAN, 1x WAN)
- 2.4 GHz Wifi
- 2x external, detachable Wifi antennas
- LTE Modem Huawei ME909u-521 (Also other Modem seen)
- 2x LTE antennas
- 1x GPS antenna
- 7x LED, 1x button
- 1x USB Connector
- 1x Serial RS232
- 1x Serial RS485
- 1x MicroSD Card

The GPL sources of the device are available at www.teltonika.lt/gpl/
and are based on OpenWRT Barrier Breaker (14.07)

Running from tftp:

The Router starts into the uboot Webupdater if the Button ist pressed
more than 3 seconds, if no Network cable is attached it starts the
uboot serial console, from there the router loads the firmware image
via tftpboot from 192.168.1.2:firmware.bin (the router has the
192.168.1.1). With bootm the loaded image will be booted.
