sandbox: eth: Add a bridge to a real network for sandbox
Implement a bridge between U-Boot's network stack and Linux's raw packet
API allowing the sandbox to send and receive packets using the host
machine's network interface.
This raw Ethernet API requires elevated privileges. You can either run
as root, or you can add the capability needed like so:
sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot
