Hi,
Sometimes, I found one of my Mellanox NIC renamed to rename6, instead of eth1. The right names of NICs in my system should be: eth0 Mellanox NIC eth1 Mellanox NIC eth2 Intel NIC eth3 Intel NIC eth4 Intel NIC eth5 Intel NIC eth0 and eth1 will combined as bond1 with mode 4. However, the current names are: eth0 Mellanox NIC rename6 Mellanox NIC eth1 Intel NIC eth2 Intel NIC eth4 Intel NIC eth5 Intel NIC And bond1 still consist of eth0 and eth1, but eth1 is Intel NIC, instead of Mellanox NIC.

It seems that udevd failed to rename eth1 to eth3, because eth1 has been enslaved by bond1. Does anyone know how to handle this problem?

Thanks.
