On the other hand, it tries to identify what data structures does DSA really need to keep and pass along to drivers, and which structures are best left for the drivers to deal privately with them. Testing has been done in the following topology: +----------------------------------+ | Board 1 br0 | | +---------+ | | / \ | | | | | | | bond0 | | | +-----+ | | | / \ | | eno0 swp0 swp1 swp2 | +---|--------|-------|-------|-----+ | | | | +--------+ | | Cable | | Cable| |Cable Cable | | +--------+ | | | | | | +---|--------|-------|-------|-----+ | eno0 swp0 swp1 swp2 | | | \ / | | | +-----+ | | | bond0 | | | | | | \ / | | +---------+ | | Board 2 br0 | +----------------------------------+ The same script can be run on both Board 1 and Board 2 to set this up: #!/bin/bash ip link del bond0 ip link add bond0 type bond mode 802.3ad ip link set swp1 down && ip link set swp1 master bond0 && ip link set swp1 up ip link set swp2 down && ip link set swp2 master bond0 && ip link set swp2 up ip link del br0 ip link add br0 type bridge ip link set bond0 master br0 ip link set swp0 master br0 Then traffic can be tested between eno0 of Board 1 and eno0 of Board 2.
