[WireGuard] LEDE / OpenWrt test - on TP-Link841Nv11 - 15MBs and crash

last night we tested Wireguard with LEDE on a fairly weak mashine - TP
Link 841N v11.1 with 4MB flash, 32MB ram, and 650 MHz cpu.
we choose this router model because we have some hundred of them
deployed in our free wifi for the public networks around our city. (as
mentioned before Freifunk Freiburg https://freiburg.freifunk.net ) We
were interestet in Performance and what we (maybe) can do with wireguard

we described it in detail here
https://forum.freifunk.net/t/lede-test-wireguard-und-blanko-durchsatz-tp841nv11-1-und-bug/13163

brief summary - sharing of experiences
netifd crashed via iperf3 test from   laptop - 841Nv11 - 841Nv11 - laptop
iperf was running on laptops, wireguard as tunnel between 841Nv11
Routers, all connected via cable.

without wireguard, so plain routing we got 93 MBs (for refference)
and with Wireguard so far 15.5 MBs

there are clearly some heavy problems with netifd from LEDE/Openwrt ...
we simply ran in heavy load (2.6++) and out of memory

here some notes and dmesg output:
