When dumping to ssh via local ipv6 address, the ssh parameter in kdump.conf is supposed to have the form like ssh user@fe80::cc1:8bff:fe90:b95f%eth0 where "%eth0" is an existing network interface supporting ipv6. However, there are 3 problems in enabling ipv6: 1) The get_remote_host function in kdump-lib.sh currently doesn't remove the network interface in the ipv6 address, causing the ip command in kdump_install_net function to fail, leading to a "Bad kdump location" message. 2) The kdump_setup_ifname function in dracut-module-setup.sh would add 'kdump-' prefix to network interfaces with name like 'eth*', causing ssh target specified in kdump.conf invalid while dumping process. 3) ssh target with 'kdump-' prefixed interface name is not in known_hosts while dumping, leading to ssh connection failure. This patch series handles the problems above.
