[net,0/8] Netfilter fixes for net

Hi,

The following patchset contains Netfilter fixes for net:

1) Nicolas Dichtel updates MAINTAINERS file to add Netfilter IRC channel.

2) Skip non-IPv6 packets in nft_exthdr.

3) Skip non-TCP packets in nft_osf.

4) Skip non-TCP/UDP packets in nft_tproxy.

5) Memleak in hardware offload infrastructure when counters are used
   for first time in a rule.

6) The VLAN transfer routine must use FLOW_DISSECTOR_KEY_BASIC instead
   of FLOW_DISSECTOR_KEY_CONTROL. Moreover, make a more robust check
   for 802.1q and 802.1ad to restore simple matching on transport
   protocols.

7) Fix bogus EPERM when listing a ruleset when table ownership flag
   is set on.

8) Honor table ownership flag when table is referenced by handle.

Thank you!
