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:
eth0Mellanox NIC
eth1Mellanox NIC
eth2Intel NIC
eth3Intel NIC
eth4Intel NIC
eth5Intel NIC
eth0 and eth1 will combined as bond1 with mode 4. However, the current
names are:
eth0Mellanox NIC
rename6 Mellanox NIC
eth1Intel NIC
eth2Intel NIC
eth4Intel NIC
eth5Intel NIC
And bond1 still consist of eth0 and eth1, but eth1 is Intel NIC, instead
of Mellanox NIC.
