Pull networking fixes from David Miller:

 1) Fix IGMP handling wrt VRF, from David Ahern.

 2) Fix timer access to freed object in dccp, from Eric Dumazet.

 3) Use kmalloc_array() in ptr_ring to avoid overflow cases which are
    triggerable by userspace. Also from Eric Dumazet.

 4) Fix infinite loop in unmapping cleanup of nfp driver, from Colin Ian
    King.

 5) Correct datagram peek handling of empty SKBs, from Matthew Dawson.

 6) Fix use after free in TIPC, from Eric Dumazet.

 7) When replacing a route in ipv6 we need to reset the round robin
    pointer, from Wei Wang.

 8) Fix bug in pci_find_pcie_root_port() which was unearthed by the
    relaxed ordering changes, from Thierry Redding. I made sure to get
    an explicit ACK from Bjorn this time around :-)
