From e71e0349eb32bc438fa80d8990c6f3592967d111 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Thu, 10 Jan 2008 02:56:03 -0800 Subject: [NETNS][IPV6]: Make ip6_frags per namespace. The ip6_frags is moved to the network namespace structure. Because there can be multiple instances of the network namespaces, and the ip6_frags is no longer a global static variable, a helper function has been added to facilitate the initialization of the variables. Until the ipv6 protocol is not per namespace, the variables are accessed relatively from the initial network namespace. Signed-off-by: Daniel Lezcano Signed-off-by: David S.
