napi_build_skb() reuses NAPI skbuff_head cache in order to save some
cycles on freeing/allocating skbuff_heads on every new Rx or completed
Tx.
Use napi_consume_skb() to feed the cache with skbuff_heads of completed
Tx so it's never empty.

The international version of Mi Router 4A 100M is physically
identical to the non-international one, but appears to be
using a different partitioning scheme with the "overlay"
partition being 2MiB in size instead of 1MiB. This means
the following "firmware" partition starts at a different
address and the DTS needs to be adjusted for the firmware
to work.

PCB ID: DBE00B-1.6MM
LEDs: 1 RGB LED
Power: 12 VDC, 1.5 A
Connector type: barrel
Bootloader: U-Boot
Installation
-----------------
1. Downgrade stock (Beeline) firmware to v.1.0.02;
2. Give factory OpenWrt image a shorter name, e.g. 1001.img;
3. Upload and update the firmware via the original web interface.
Remark: You might need make the 3rd step twice if your running firmware
is booted from the Slot 1 (Sercomm0 bootflag). The stock firmware
reverses the bootflag (Sercomm0 / Sercomm1) on each firmware update.
Revert to stock
---------------
1. Change the bootflag to Sercomm1 in OpenWrt CLI and then reboot:
printf 1 | dd bs=1 seek=7 count=1 of=/dev/mtdblock3
2. Optional: Update with any stock (Beeline) firmware if you want to
overwrite OpenWrt in Slot 0 completely.

sercomm-payload.py - already exists in OpenWrt
sercomm-pid.py - new, the part of this pull request
sercomm-kernel-header.py - new, the part of this pull request
2. This device (same as other Sercomm S2,S3-based devices) requires
special LZMA and LOADADDR settings for successful boot:
LZMA_TEXT_START=0x82800000
KERNEL_LOADADDR=0x81001000
LOADADDR=0x80001000
3. This device (same as several other Sercomm-based devices - Beeline,
Netgear, Etisalat, Rostelecom) has partition map (mtd1) containing
real partition offsets, which may differ from device to device
depending on the number and location of bad blocks on NAND.
"fixed-partitions" is used if the partition map is not found or
corrupted. This behavour (it's the same as on stock firmware) is
provided by MTD_SERCOMM_PARTS module.

GPIO 1 on the RTL8231 is used to force the PoE MCU to disable power
outputs. It is not used by any driver, but if accidentally set low,
PoE outputs are disabled. This situation is hard to debug, and
requires knowledge of the Broadcom PoE protocol used by the MCU.
To prevent this situation, hog it as an output high. This is
consistent with the ZyXel GS1900 series handles it.

At least two AX820 hardware variants are known to exist, but they cannot
be distinguished (same hardware revision, no specific markings).
They appear to have the same LED hardware, but wired differently:
- One has a red system LED at GPIO 15, a green wlan2g LED at GPIO 14 and
a blue wlan5g LED at GPIO 16;
- The other only offers a green system LED at GPIO 15, with GPIO 14 and
16 being apparently not connected
Finally, a Yuncore datasheet says the canonical wiring should be:
- Blue wlan2g GPIO 14, green system GPIO 15, red wlan5g GPIO 16
All GPIOs are tied to a single RGB LED which is exposed via lightpipe on
the device front casing.
Considering the above, this patch exposes all three LEDs, preserves the
common system LED (GPIO 15) as the openwrt status LED, and removes the
color information from the LEDs names since it is not consistent across
hardware. The LED naming is made consistent with other YunCore devices.
A note is added in DTS to ensure this information is always available
and prevent unwanted changes in the future.

Enable PowerPC Book-E Watchdog Timer support. Having this enabled
in-kernel will result in procd starting it during boot.
This effectively solves the problem of the WDT in the Winbond W83793 chip
potentially resetting the system during sysupgrade, which could result
in an unbootable device. While the driver is modular, resulting in procd
not starting the WDT during boot (because that happens before kmod
load), the WDT handover during sysupgrade results in the WDT being
started. This normally shouldn't be a problem, but the W83793 WDT does
not like procd's defaults, nor the handover happening during sysupgrade.

the pairing buttons have to have pressed for at least half a second,
it doesn't matter on which plc device (master or slave) first
it is possible to pair the devices without the button-pairing requirement
simply by pressing reset on the slave device. This will default to the
firmware settings, which is also how the plc_basic script is setting up
the master device, i.e. configuring it to firmware defaults
the PL-E56P slave PLC has its dedicated 4MByte SPI, thus it is capable
to store all firmware currently available. Note that some other
slave devices are not guarantied to have the capacity for the newer
~1MByte firmware blobs!

Since 4e0c54bc5b ("kernel: add support for kernel 5.4"),
the spi-nor limit 4k erasesize to spi-nor chips below a configured size
patch has not functioned as intended.
For uniform erasesize SPI-NOR devices, both
nor->erase_opcode & mtd->erasesize are used in erase operations.
These are set before, and not modified by, this
CONFIG_MTD_SPI_NOR_USE_4K_SECTORS_LIMIT patch.
Thus, an SPI-NOR device with CONFIG_MTD_SPI_NOR_USE_4K_SECTORS will
always use 4k erasesize (where the device supports it).

DGS-1210 switches support dual image, with each image composed of a
kernel and a rootfs partition. For image1, kernel and rootfs are in
sequence. The current OpenWrt image (written using a serial console),
uses those partitions together as the firmware partition, ignoring the
partition division. The current OEM u-boot fails to validate image1 but
it will only trigger firmware recovery if both image1 and image2 fail,
and it does not switch the boot image in case one of them fails the
check.
The OEM factory image is composed of concatenated blocks of data, each
one prefixed with a 0x40-byte cameo header. A normal OEM firmware will
have two of these blocks (kernel, rootfs). The OEM firmware only checks
the header before writing unconditionally the data (except the header)
to the correspoding partition.
The OpenWrt factory image mimics the OEM image by cutting the
kernel+rootfs firmware at the exact size of the OEM kernel partition
and packing it as "the kernel partition" and the rest of the kernel and
the rootfs as "the rootfs partition". It will only work if written to
image1 because image2 has a sysinfo partition between kernel2 and
rootfs2, cutting the kernel code in the middle.
Steps to install:
1) switch to image2 (containing an OEM image), using web or these CLI
commands:
- config firmware image_id 2 boot_up
- reboot
2) flash the factory_image1.bin to image1. OEM web (v6.30.016)
is crashing for any upload (ssh keys, firmware), even applying OEM
firmwares. These CLI commands can upload a new firmware to the other
image location (not used to boot):
- download firmware_fromTFTP <tftpserver> factory_image1.bin
- config firmware image_id 1 boot_up
- reboot
To debrick the device, you'll need serial access. If you want to
recover to an OpenWrt, you can replay the serial installation
instructions. For returning to the original firmware, press ESC during
the boot to trigger the emergency firmware recovery procedure. After
that, use D-Link Network Assistant v2.0.2.4 to flash a new firmware.
The device documentation does describe that holding RESET for 12s
trigger the firmware recovery. However, the latest shipped U-Boot
"2011.12.(2.1.5.67086)-Candidate1" from "Aug 24 2021 - 17:33:09" cannot
trigger that from a cold boot. In fact, any U-Boot procedure that relies
on the RESET button, like reset settings, will only work if started from
a running original firmware. That, in practice, cancels the benefit of
having two images and a firmware recovery procedure (if you are not
consider dual-booting OpenWrt).

supported.
Cage 10F is fully supported with an I2C bus and sfp handle. Linux
automatically handles enabling or disabling the TX laser.
Cage 9F is only parially supported, without the sfp handle. The SDA
line is hogged as an input, so that it remains high. SCL transitions
sould not affect modules connected to this cage. The default value of
the tx-disable line is high (active). It is exported as a gpio, but
the laser is off by default. To enable the laser:
echo 0 > /sys/class/gpio/sff-p9-tx-disable/value
Thus, both modules can be used for networking, but only 10F will be
able to detect and identify a plugged in SFP module.

Add support for the Engenius EWS2910P PoE switch. This is an RTL8380
based switch with two SFP slots, and PoE 802.3af one every RJ-45 port.
The specs say 802.3af, but the vendor firmware configures the PSE for
a budget of 31W, indicating 802.3at support.
Specifications:
---------------
* SoC: Realtek RTL8380M
* Flash: 32 MiB SPI flash Macronix MX25L25635E
* RAM: 256 MiB (As reported by bootloader)
* Ethernet: 16x 10/100/1000 Mbps with PoE
2x SFP slots
* Buttons: 1 "Reset" button on front panel
1 "LED mode: button on front panel
1 "On/Off" Toggle switch on the back
* Power: 48V-54V DC barrel jack
* UART: 1 serial header (JP1) with populated 2.54mm pitch header
Labeled GRTV for ground, rx, tx, and 3.3V respectively
* PoE: 1 STM ST32F100 microcontroller
2 BCM59111 PSE chips
Works:
------
- (8) RJ-45 ethernet ports
- Switch functions
- LEDs and buttons
Not yet enabled:
----------------
- SFP ports (will be enabled in a subsequent change)
- Power-over-Ethernet (requires realtek-poe package)
Install via web interface:
-------------------------
The factory firmware will accept and flash the initramfs image. It is
recommended to flash to "Partition 0". Flashing to "Partition 1" is
not supported at this point.
The factory web GUI will show the following warning:
" Warning: The firmware version is v0.00.00-c0.0.00
The firmware image you are uploading is older than the current
firmware of the switch. The device will reset back to default
settings. Are you sure you want to proceed?"
This is expected when flashing OpenWrt. After the initramfs image
boots, flash the -sysupgrade using either the commandline or LuCI.
Install via serial console/tftp:
--------------------------------
The u-boot firmware will not stop the boot, regardless of which key is
pressed. To access the u-boot console, ground out the CLK (pin 16) of
the ROM (U22) when u-boot is reading the linux image. If timed
correctly, the image CRC will fail, and u-boot will drop to a shell:
> rtk network on
> setenv ipaddr <address of tftp server>
> tftp $(freemem) <name-of-initramfs-image.bin>
> bootm
Then flash the -sysupgrade using either the commandline or luci.
