# Uses following information from "/etc/sysconfig/network-scripts/ifcfg-$1":
#  IPV6INIT=yes|no: controls IPv6 configuration for this interface
#  IPV6ADDR=<IPv6 address>[/<prefix length>]: specify primary static IPv6 address
#  IPV6ADDR_SECONDARIES="<IPv6 address>[/<prefix length>] ..." (optional)
#  IPV6_MTU=<MTU for IPv6>: controls IPv6 MTU for this link (optional)
