Hi Jason,
I get "Failed to give packet to userspace from peer x" on my Solidrun
Cubox I4pro with very poor wifi connection.
So i connect to my internal wireguard server via wifi. Run iperf3.
Often I get Failed to give packet to userspace from peer x. See full
log below.
I noticed it seems to happen before the last interval of iperf.
Running F26 with stock kernel 4.12.13-300.fc26.armv7hl
WireGuard 0.0.20170918-9-g31ae6e6: Fails often
