here some more tests with fastd directly, i dont see any big difference
between salsa20 and salsa2012, but i big difference in direction ...
which is somehow new for me.

i will not do the different wireguard testings with different ciphers,
as i am still struggling in building valid reproducable kmod..ipk
packages for LEDE

so i think fastd testing is finished by this (which at all only was to
compare to our existing setup) - a small notice : OpenWRT Wiki was wrong
with CPU speed of TPlink841v11 - it is not 560MHz, it is 650Mhz - if
somebody ever want to compare another embedded device
