edma_read_append_stats() gets called from two places in the driver.
The first place is the kernel timer that periodically updates
the statistics, so nothing gets lost due to overflows.
The second one it's part of the userspace ethtool ioctl handler
to provide up-to-date values.
For this configuration, the use of spin_lock() is not sufficient
and as per:
<https://mirrors.edge.kernel.org/pub/linux/kernel/people/rusty/kernel-locking/c214.html>
the locking has to be upgraded to spin_lock_bh().

The ar40xx driver currently panics in case no QCA807x PHY has been
successfully probed. This happens when the external PHY is still
in reset when probing the ar40xx switch driver.
Note that this patch does not fix the root cause, ar40xx_probe now
simply fails instead of causing a kernel panic due to a nullpointer
dereference.

The Linksys EA8300 is based on QCA4019 and QCA9888 and provides three,
independent radios. NAND provides two, alternate kernel/firmware
images with fail-over provided by the OEM U-Boot.
Installation:
"Factory" images may be installed directly through the OEM GUI.
Hardware Highlights:
* IPQ4019 at 717 MHz (4 CPUs)
* 256 MB NAND (Winbond W29N02GV, 8-bit parallel)
* 256 MB RAM
* Three, fully-functional radios; `iw phy` reports (FCC/US, -CT):
* 2.4 GHz radio at 30 dBm
* 5 GHz radio on ch. 36-64 at 23 dBm
* 5 GHz radio on ch. 100-144 at 23 dBm (DFS), 149-165 at 30 dBm
#{ managed } <= 16, #{ AP, mesh point } <= 16, #{ IBSS } <= 1
* All two-stream, MCS 0-9
* 4x GigE LAN, 1x GigE Internet Ethernet jacks with port lights
* USB3, single port on rear with LED
* WPS and reset buttons
* Four status lights on top
* Serial pads internal (unpopulated)
"Linksys Dallas WiFi AP router based on Qualcomm AP DK07.1-c1"
Implementation Notes:
The OEM flash layout is preserved at this time with 3 MB kernel and
~69 MB UBIFS for each firmware version. The sysdiag (1 MB) and
syscfg (56 MB) partitions are untouched, available as read-only.
Serial Connectivity:
Serial connectivity is *not* required to flash.
Serial may be accessed by opening the device and connecting
a 3.3-V adapter using 115200, 8n1. U-Boot access is good,
including the ability to load images over TFTP and
either run or flash them.
Looking at the top of the board, from the front of the unit,
J3 can be found on the right edge of the board, near the rear

* Bluetooth; Qualcomm CSR8811 (potentially conected to serial1)
Other Notes:
https://wikidevi.com/wiki/Linksys_EA8300 states
FCC docs also cover the Linksys EA8250. According to the
RF Test Report BT BR+EDR, "All models are identical except
for the EA8300 supports 256QAM and the EA8250 disable 256QAM."

Added basic support to get the device up and running for a sysupgrade
image only.
There is currently no way back to factory firmware, so this is a one-way
street to OpenWRT.
Install from factory condition is convoluted, and may brick your device:
1) Enable SSH and disable the CLI on the factory device from the web user
interface (Management->Advanced)
2) Reboot the device
3) Override the default, limited SSH shell:
a) Get into the ssh shell:
ssh admin@192.168.1.1 /bin/sh --login
b) Change the dropbear script to disable the limited shell. At the
empty command prompt type:
sed -i '/login_ssh/s/^/#/g’ dropbear
/etc/init.d/dropbear restart
exit
4) ssh in to a (now-) normal OpenWRT SSH session
5) Flash your built image
a) scp openwrt-ipq40xx-engenius_ens620ext-squashfs-sysupgrade.bin
admin@192.168.1.1:/tmp/
b) ssh admin@192.168.1.1
c) sysupgrade -n
/tmp/openwrt-ipq40xx-engenius_ens620ext-squashfs-sysupgrade.bin
6) After flash completes (it may say "Upgrade failed" followed by
"Upgrade completed") and device reboots, log in to newly flashed
system. Note you will now need to ssh as root rather than admin.

script. It is located in the 'scripts/flashing' subdirectory of the
OpenWRT tree.
2. Assign yourself the IP address 192.168.178.10/24. Connect your
Computer to one of the boxes LAN ports.
3. Connect Power to the Box. As soon as the LAN port of your computer
shows link, load the U-Boot to the box using following command.
> ./eva_ramboot.py --offset 0x85000000 192.168.178.1 uboot-fritz3000.bin
4. The U-Boot will now start. Now assign yourself the IP address
192.168.1.70/24. Copy the OpenWRT initramfs (!) image to a TFTP
server root directory and rename it to 'FRITZ3000.bin'.
5. The Box will now boot OpenWRT from RAM. This can take up to two
minutes.
6. Copy the U-Boot and the OpenWRT sysupgrade (!) image to the Box using
scp. SSH into the Box and first write the Bootloader to both previous
kernel partitions.

This patch fixes a problem that was discovered during DSA
development. On the MR33, the link change events from the
external AR8035-PHY would never make it to the qca8k driver.
The issue turned out to be a misplaced memcpy that was copying
over the zero-initialized irq table, when it should have been
set to PHY_POLL. Hence this patch moves the memcpy after the
array has been initialized.

- Select the connectivity tab on the left
- In the manual update box on the right
- Select browse, and browse to

- Click update.
- Read and accept the warning
- The router LED will start blinking. When the router LED goes solid, you
can now navigate to 192.168.1.1 to your new OpenWrt installation.
Sysupgrade:
- Flash the sysupgrade image as usual. Please: try to do a reset everytime
you can (doing it with LuCI is easy and can be done in the same step).
Recovery (Automatic):
- If the device fails to boot after install or upgrade, whilst the unit is
turned on:
1 - Wait 15 seconds
2 - Switch Off and Wait 10 seconds
3 - Switch on
4 - Repeat steps 1 to 3, 3 times then go to 5.
5 - U-boot will have now erased the failed update and switched back to the
last working firmware - you should be able to access your router on
LAN.
Recovery (Manual):
- The steps for manual recovery are the same as the generic u-boot tftp
client method.
Back To Stock:
- Use the generic recovery using the tftp client method to flash the
"civic.img". Also you can strip-and-pad the original image and use
the generic "mtd" method by flashing over the "kernel" partition.
* Just be careful to flash in the partition that the device is currently
booted.
