Pull networking fixes from David Miller:
 "Mostly fixing some light fallout from the changes that went into the
  merge window.

   1) Fix memory leaks on network namespace teardown in netfilter, from
      Liping Zhang.

   2) When comparing ipv6 nexthops, we have to take the lightweight
      tunnel state into account as well. From David Ahern.

   3) Fix socket option object length check in the new TLS code, from
      Matthias Rosenfelder.

   4) Fix memory leak in nfp driver flower support, from Jakub Kicinski.

   5) Several netlink attribute validation fixes in cfg80211, from
      Srinivas Dasari.

   6) Fix context array leak in virtio_net, from Jason Wang.

   7) SKB use after free in hns driver, from Yusheng Lin.

   8) Fix socket leak on accept() in RDS, from Sowmini Varadhan. Also
      add a WARN_ON() to sock_graft() so other protocol stacks don't
      trip over this as well"

@ -55,7 +55,7 @@ IPIP, SIT, GRE, UDP Tunnel, and Remote Checksum Offloads
In addition to the offloads described above it is possible for a frame to
contain additional headers such as an outer tunnel. In order to account
for such instances an additional set of segmentation offload types were
introduced including SKB_GSO_IPIP, SKB_GSO_SIT, SKB_GSO_GRE, and
introduced including SKB_GSO_IPXIP4, SKB_GSO_IPXIP6, SKB_GSO_GRE, and
SKB_GSO_UDP_TUNNEL. These extra segmentation types are used to identify
cases where there are more than just 1 set of headers. For example in the
case of IPIP and SIT we should have the network and transport headers moved
