From fe7ca2e1e847b65c12d245cbf402af89da96888a Mon Sep 17 00:00:00 2001 From: Brian Haley Date: Wed, 4 Mar 2009 03:18:11 -0800 Subject: IPv6: add "disable" module parameter support to ipv6.ko Add "disable" module parameter support to ipv6.ko by specifying "disable=1" on module load. We just do the minimum of initializing inetsw6[] so calls from other modules to inet6_register_protosw() won't OOPs, then bail out. No IPv6 addresses or sockets can be created as a result, and a reboot is required to enable IPv6. Signed-off-by: Brian Haley Signed-off-by: David S.
