[PATCH] ramips: add support for TOTOLINK X5000R

[Bas Mevissen]

Hi,

Thanks for creating this patch. Got my X5000R today. Before flashing it 
to OpenWRT, can you please tell me whether you (or anyone else) did 
performance measurements with the original and the OpenWRT firmware?

I measured over 600mbit/s with WPA3 when on my desk, next to a notebook 
with Intel WiFi6 AX200 card. So I hope I can keep that performance when 
on OpenWRT.

(measured with iperf3, tcp default settings, from wireless 5GHz to PC 
wired to WAN in both directions)

Many thanks in advance,

Bas.
