Pull networking fixes from David Miller:
 "Some straggler bug fixes here:

   1) Netlink_sendmsg() doesn't check iterator type properly in mmap
      case, from Ken-ichirou MATSUZAWA.

   2) Don't sleep in atomic context in bcmgenet driver, from Florian
      Fainelli.

   3) The pfkey_broadcast() code patch can't actually ever use anything
      other than GFP_ATOMIC.  And the cases that right now pass
      GFP_KERNEL or similar will currently trigger an RCU splat.  Just
      use GFP_ATOMIC unconditionally.  From David Ahern.

   4) Fix FD bit timings handling in pcan_usb driver, from Marc
      Kleine-Budde.

   5) Cache dst leaked in ip6_gre tunnel removal, fix from Huaibin Wang.

   6) Traversal into drivers/net/ethernet/renesas should be triggered by
      CONFIG_NET_VENDOR_RENESAS, not a particular driver's config
      option.  From Kazuya Mizuguchi.

   7) Fix regression in handling of igmp_join errors in vxlan, from
      Marcelo Ricardo Leitner.

   8) Make phy_{read,write}_mmd_indirect() properly take the mdio_lock
      mutex when programming the registers.  From Russell King.

   9) Fix non-forced handling in u32_destroy(), from WANG Cong.

  10) Test the EVENT_NO_RUNTIME_PM flag before it is cleared in
      usbnet_stop(), from Eugene Shatokhin.

  11) In sfc driver, don't fetch statistics firmware isn't capable of,
      from Bert Kenward.

  12) Verify ASCONF address parameter location in SCTP, from Xin Long"

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  sctp: donot reset the overall_error_count in SHUTDOWN_RECEIVE state
  sctp: asconf's process should verify address parameter is in the beginning
  sfc: only use vadaptor stats if firmware is capable
  net: phy: fixed: propagate fixed link values to struct
  usbnet: Get EVENT_NO_RUNTIME_PM bit before it is cleared
  drivers: net: xgene: fix: Oops in linkwatch_fire_event
  cls_u32: complete the check for non-forced case in u32_destroy()
  net: fec: use reinit_completion() in mdio accessor functions
  net: phy: add locking to phy_read_mmd_indirect()/phy_write_mmd_indirect()
  vxlan: re-ignore EADDRINUSE from igmp_join
  net: compile renesas directory if NET_VENDOR_RENESAS is configured
  ip6_gre: release cached dst on tunnel removal
  phylib: Make PHYs children of their MDIO bus, not the bus' parent.
  can: pcan_usb: don't provide CAN FD bittimings by non-FD adapters
  net: Fix RCU splat in af_key
  net: bcmgenet: fix uncleaned dma flags
  net: bcmgenet: Avoid sleeping in bcmgenet_timeout
  netlink: mmap: fix tx type check
