From fadf6bf06069138f8e97c9a963be38348ba2708b Mon Sep 17 00:00:00 2001 From: "Templin, Fred L" Date: Tue, 11 Mar 2008 18:35:59 -0400 Subject: [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.
