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.

Check if we're in NAPI context when refilling rx. Normally we're almost
always running in NAPI context. Dispatch to napi_alloc_frag() directly
instead of relying on netdev_alloc_frag() which does the same but with
the overhead of local_bh_disable/enable.

We can increase the efficiency of rx path by using buffers to receive
packets then build SKBs around them just before passing into the network
stack. In contrast, preallocating SKBs too early reduces CPU cache
efficiency.
Performance is slightly increased but the changes allow more
potential optimizations.

bmips is using Broadcom B53 DSA driver which means the ethernet driver
must compensate for 6 bytes tags from the internal switch.
This means using NET_IP_ALIGN actually misaligns the skb, lowering
performance significantly. Therefore napi_alloc_skb() which uses
NET_IP_ALIGN is changed to netdev_alloc_skb().
Performance in iperf3 is increased from ~47Mbps to 52Mbps.

0x000000fb0000-0x000001000000 : "Private"
```
The kernel partition will be replaced with the OpenWrt image, the other
partitions are left untouched.
"Config2" seems to be the config storage used by the stock firmware.
"Private" is a 320kB empty JFFS2 partition that comes with the stock
firmware. One can get a larger space for OpenWrt by merging it with
"Kernel".
OpenWrt flash layout:
```
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"

0x000000fb0000-0x000001000000 : "private_stock"
```
The OpenWrt image must have 96 bytes of padding in the header.
MAC addresses on OEM firmware:
| | location on the flash | notes |
|------ |----------------------- |---------- |
| lan (eth2) | factory + 0xe000 | on label |
| wan (eth3) | factory + 0xe006 | |
| 2.4g (rax0) | not on flash | lan + 1 |
| 5g (ra0) | not on flash | lan + 2 |
Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
the u-boot-env partition, but they are not used. OpenWrt calculates
Wifi Mac addresses based on the LAN Mac.
Flash and test instructions:
Flash the encrypted image (available in the OpenWrt forum) through the
stock D-Dink web interface.
1. Open the case, and solder the 4-pin header near the WAN port.
2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
the settings mentioned above.
4. Setup a TFTP server on your PC that can serve
`xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
5. Connect any LAN port to your PC and set a static IPv4 address to
192.168.0.101 (netmask 255.255.255.0).
6. Power on the device and keeps pressing 1 until you see the prompt.
7. Use default IP addresses and enter the file name accordingly, then hit
enter.
8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
you need to change your PC network adapter to use DHCP in order to access
LUCI.
9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
You can try OpenWrt without having to overwrite the stock firmware, a
reboot clears all changes.
10. Optionally, backup the stock firmware (the "firmware" partition) in
Luci.
11. To permantly install OpenWrt to the device , click
on "System -> Backup/Flash Firmware" in Luci and flash
`xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`
Known problems:
* WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
you need to config it manually in LUCI.
* If you see jffs2 related warnings/errors after updating from the stock
web interface, you need to do a reset in LUCI. The error will be gone after
a cold reboot.

This fixes spurious boot-errors with some ath79 MIPS 74Kc boards such
as the AC Lite as well as Archer C7 v2.
The missing barrier leads to the icache flush being executed before the
dcache writeback, which results in the CPU executing the dummy infinite

Applying this patch from upstream ensures the dcache is written back

Forward-port from ar71xx target the board introduced in commit
eb9e3651dd (" ar71xx: add support for the MikroTik RB911-2Hn/5Hn
boards"). Citing:
The patch adds support for the MikroTik RB911-2Hn (911 Lite2)
and the RB911-5Hn (911 Lite5) boards:
https://mikrotik.com/product/RB911-2Hnhttps://mikrotik.com/product/RB911-5Hn
The two boards are using the same hardware design, the only difference
between the two is the supported wireless band.
Specifications:
* SoC: Atheros AR9344 (600MHz)
* RAM: 64MiB
* Storage: 16 MiB SPI NOR flash
* Ethernet: 1x100M (Passive PoE in)
* Wireless: AR9344 built-in wireless MAC, single chain
802.11b/g/n (911-2Hn) or 802.11a/g/n (911-5Hn)
Notes:
* Older versions of these boards might be equipped with a NAND
flash chip instead of the SPI NOR device. Those boards are not
supported (yet).[1]
* The MikroTik RB911-5HnD (911 Lite5 Dual) board also uses the
same hardware. Support for that can be added later with little
effort probably.[2]
