└─>IP6 tables support (required for filtering)
In linux kernel since version 2.6.12  
ip6tables is a general, extensible packet identification framework.
Currently only the packet filtering and packet mangling subsystem
for IPv6 use this, but connection tracking is going to follow.
Say 'Y' or 'M' here if you want to use either of those.

To compile it as a module, choose M here. If unsure, say N.
