The following patchset contains Netfilter fixes for your net tree:

1) Remove a direct dependency with IPv6 introduced by the
   sip_external_media feature, from Alin Nastac.

2) Fix bogus ENOENT when removing interval elements from set.

   behaviour, this partially fixes a checksum validation bug
   from the SCTP connection tracking, from Xin Long.

4) Fix undefined reference to symbol in xt_TEE, due to missing
   Kconfig dependencies, from Arnd Bergmann.

5) Check for NULL in skb_header_pointer() calls in ip6t_shr,
   from Kangjie Lu.

   a transaction.

8) Remove duplicated transition in flowtable diagram in the existing
   documentation.

9) Missing .release_ops call from error path in newrule() which
