We met a problem that eth0 ends up being eth1 and eth1 being eth0 between 1st and 2nd kernel. Because we pass ifname=eth0:$mac to force it's named eth0 and since "eth0"is already taken by the other NIC, udev fails to bring up the NIC we want, thus kdump fails. kernel assigned network interface names are not persistent. So if first kernel is using kernel assigned interface names, then force it to use "kdump-" prefixed names in second kernel. For ethX, we put a prefix "kdump-" before it, so in 2nd kernel, ethX will name to "kdump-ethX". So that we can avoid the naming conflict. We only need to change the ethernet card name, that means, for bridge, vlan, bond, team devices' names , we never prefix them. Because these names are assigned when they're created by userspace.
