====================
Netfilter fixes for net
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.
3) Set transport_header from br_netfilter to mimic the stack
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.
6) Fix bogus EBUSY when removing an existing conntrack helper from
a transaction.
7) Fix module autoload of the redirect extension.
8) Remove duplicated transition in flowtable diagram in the existing
documentation.
9) Missing .release_ops call from error path in newrule() which
results module refcount leak, from Taehee Yoo.
