Installed Arch Linux on to Pi ZeroW with attached enc28j60 interface, configured.
$this->bbcode_second_pass_code('', '
dtparam=spi=on
dtoverlay=enc28j60
')
When I ping Pi from any host in the network, it's OK, no packet loss, but when I try to ping any host from Pi, then I got 50 to 80% packet loss. Also it is almost impossible to use the interface.
Tried Pi OS from https://www.raspberrypi.org/software/operating-systems/ with same config, and ping works both ways without packet loss.
Interface is also working fine.
Looked at driver version, it's the same for both systems.
Any thoughts?
