[PATCH] module-setup: Add permanent option to detect static ip address or not

[Minfei Huang]

Dracut will die in the situation that dracut detects to use dhcp to get
ip address, but kdump passes the ip address to it.

The command "ip addr show dev $dev permanent" will only show the static
ip. Thues kdump cannot get the ip address in kdump_static_ip, if we use
dhcp to setup the network.
