Birger Koblitz 88f7a29f99 ramips: add support for Edimax EW-7476RPC / EW-7478AC
SoC:	MediaTek MT7620a @ 580MHz
RAM:	64M (Winbond W9751G6KB-25)
FLASH:	8MB (Macronix)
WiFi:	SoC-integrated: MediaTek MT7620a bgn
WiFi:	MediaTek MT7612EN nac
GbE:	1x (RTL8211E)
BTN:	WPS - RFKILL/RF 50%/RF 100% toggle
LED:	- Wifi 5g (blue)
	- Wifi 2g (blue)
	- Crossband (green)
	- Power (green)
	- WPS (green)
	- LAN (Green)
UART:	UART is present as Pads with throughholes on the PCB. They are
	located next to the switch for the wifi configuration
	3.3V - RX - GND - TX / 57600-8N1
	3.3V is the square pad

Installation
------------
Update the factory image via the web-interfaces (by default:
192.168.9.2/24).

------------
Update the factory image via the web-interfaces (by default:
http://edimaxext.setup)
Or push wpa button on power on and send firmware via tftp to 192.168.1.6

The EW-7478AC is identical to the EW-7476RPC, except instead of 2 internal
antennas it has 2 external ones.

Felix Fietkau b605a84a74 ramips: ethernet: unify tx descriptor buffer splitting
A buffer is split into multiple descriptors if it exceeds 16 KB.
Apply the same split for the skb head as well (to deal with corner cases
on fraglist support)

Felix Fietkau 0c285bd081 ramips: ethernet: use own page_frag_cache
Using the NAPI or netdev frag cache along with other drivers can lead to
32 KiB pages being held for a long time, despite only being used for
very few page fragment.
This can happen if the ethernet driver grabs one or two fragments for rx
ring refill, while other drivers use (and free up) the remaining
fragments. The 32 KiB higher-order page can only be freed once all users
have freed their fragments, which only happens after the rings of all
drivers holding the fragments have wrapped around.

Depending on the traffic patterns, this can waste a lot of memory and
look a lot like a memory leak

Felix Fietkau 9a4253b81f ramips: improve ethernet driver performance with GRO/TSO
GRO stores packets as fraglist. If they are routed back to the ethernet
device, they need to be re-segmented if the driver does not support
sending fraglists.
Add the missing support for that, along with a missing feature flag that
allows full routed GRO->TSO offload.
Considerably reduces CPU utilization for routing

Mathias Kresin 5da2c68d00 ramips: mt7621: fix mtu setting with kernel 4.14
Since kernel 4.10 commit 61e84623ace3 ("net: centralize net_device
min/max MTU checking"), the range of mtu is [min_mtu, max_mtu], which
is [68, 1500] by default.

It's necessary to set a max_mtu if a mtu > 1500 is supported.
