Support BESS protocol (for UML) #281

Closed AkihiroSuda closed 2 years ago

AkihiroSuda commented 2 years ago

BESS protocol transferrs L2 packets as AF_UNIX SOCK_SEQPACKET . BESS protocol has been used by the vector network interfaces of User Mode Linux (UML).

(terminal 1) $ slirp4netns --target-type=bess /tmp/bess.sock
(terminal 2) $ linux.uml vec0:transport=bess,dst=/tmp/bess.sock,depth=128,gro=1 root=/dev/root rootfstype=hostfs init=/bin/bash mem=2G
(terminal 2: UML)$ ip addr add 10.0.2.100/24 dev vec0
(terminal 2: UML)$ ip link set vec0 up
(terminal 2: UML)$ ip route add default via 10.0.2.2
