Set the names of the Ethernet interfaces that are exposed from a first boot so they are aligned with those described by Mellanox/NVIDIA documentation for the BF3. Those tmfifo and oob interface names are describeded at: https://docs.nvidia.com/networking/display/bluefielddpuosv460/host-side+interface+configuration When running the native Ubuntu on the BF3 board, the following udev rules are set: $ cat /etc/udev/rules.d/91-tmfifo_net.rules SUBSYSTEM=="net", ACTION=="add", DEVPATH=="/devices/platform/MLNXBF01:00/virtio1/net/eth[0-9]", NAME="tmfifo_net0" $ cat /etc/udev/rules.d/92-oob_net.rules SUBSYSTEM=="net", ACTION=="add", DEVPATH=="/devices/platform/MLNXBF17:00/net/e*", NAME="oob_net0", RUN+="/sbin/sysctl -w net.ipv4.conf.oob_net0.arp_notify=1" The default CX ports of the BF3 are: ubuntu@bf$ ip link show p0 4: p0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether a0:88:c2:xx:xx:xx brd ff:ff:ff:ff:ff:ff altname enp3s0f0np0 ubuntu@bf$ ip link show p1 5: p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether a0:88:c2:xx:xx:xx brd ff:ff:ff:ff:ff:ff altname enp3s0f1np1 Signed-off-by: Vincent Jardin <vjardin@free.fr> Signed-off-by: Julien Olivain <ju.o@free.fr>
