Pull more networking fixes from David Miller:
 "Some more bug fixes have trickled in, we have:

  1) Local MAC entries properly in mscc driver, from Allan W. Nielsen.

  2) Eric Dumazet found some more of the typical "pskb_may_pull() -->
     oops forgot to reload the header pointer" bugs in ipv6 tunnel
     handling.

  3) Bad SKB socket pointer in ipv6 fragmentation handling, from Herbert
     Xu.

  4) Overflow fix in sk_msg_clone(), from Vakul Garg.

  5) Validate address lengths in AF_PACKET, from Willem de Bruijn"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  qmi_wwan: Fix qmap header retrieval in qmimux_rx_fixup
  qmi_wwan: Add support for Fibocom NL678 series
  tls: Do not call sk_memcopy_from_iter with zero length
  ipv6: tunnels: fix two use-after-free
  Prevent overflow of sk_msg in sk_msg_clone()
  packet: validate address length
  net: netxen: fix a missing check and an uninitialized use
  tcp: fix a race in inet_diag_dump_icsk()
  MAINTAINERS: update cxgb4 and cxgb3 maintainer
  ipv6: frags: Fix bogus skb->sk in reassembled packets
