I changed this:
saruman:~# l /dev/net/tap0
crw-r--r-- 1 root root 10, 200 Jan 10 10:36 /dev/net/tap0
saruman:~# chmod 666 /dev/net/tap0

But still get:
+ build/arty_net_or1k//qemu/or32-softmmu/qemu-system-or32 -M litex -nographic -nodefaults -monitor telnet::10000,server,nowait -serial stdio -bios build/arty_net_or1k//software/bios/bios.bin -drive if=mtd,format=qcow2,file=build/arty_net_or1k//qemu.qcow2,serial=n25q128a13 -net nic -net tap,ifname=tap0,script=no,downscript=no -gdb tcp::10001
qemu-system-or32: -net tap,ifname=tap0,script=no,downscript=no: could not configure /dev/net/tun (tap0): Operation not permitted

I guess I'll have to dig deeper into the shell script to see what's
going on.
