sctp: Make the address lists per network namespace
- Move the address lists into struct net - Add per network namespace initialization and cleanup - Pass around struct net so it is everywhere I need it. - Rename all of the global variable references into references to the variables moved into struct net Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Acked-by: Vlad Yasevich <vyasevich@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
