Also add description for struct in6_ifreq which is used for IPv6 addresses.

SIOCSIFADDR and SIOCDIFADDR can be used to add or delete IPv6 address and
pppd is using these ioctls for a long time. Surprisingly SIOCDIFADDR cannot
be used for deleting IPv4 address but only for IPv6 addresses.

Unlike SIOCGIFADDR and SIOCSIFADDR which are supported by many protocol
families, SIOCDIFADDR is supported by AF_INET6 and AF_APPLETALK only.
