[IPV6] SIT: Add PRL management for ISATAP.
This patch updates the Linux the Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) implementation. It places the ISATAP potential router list (PRL) in the kernel and adds three new private ioctls for PRL management. [Add several changes of structure name, constant names etc. - yoshfuji] Signed-off-by: Fred L. Templin <fred.l.templin@boeing.com> Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
