The driver is written in such a way that with a board defintion that
connects a fixed phy, mdio, and switch in a certain way, a kernel oops could
result because of lack of previously probed mdio bus.
This commit allows for easier debugging in this case by casting the
correct blame with serial console messages.

It's a little noisier but makes it obvious when the ar7240 switch was
connected to the MDIO bus, and to which phy device (or the failure
to do so).

NB: Error only appears with ag71xx debug messages and dynamic printk
enabled. This is probably why no one has caught it before.
Previously phy probe debug messages used old (now wrong) functions
to get the phy name for printing. There was also the chance of
a NULL pointer in the event no phy_device was found.

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).

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.

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
a bit.

Commit c312cef223dd ("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.

The motivation for this was misguided. It turns out tuning the NAPI weight could be useful for testing purposes. Therefore reverting.

This commit causes a severe regression in LAN->WAN routing performance
for several devices. This appears to be caused by the extra requirement

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.

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.
