Pull networking fixes from David Miller:

1) GRE tunnel drivers don't set the transport header properly, they also
   blindly deref the inner protocol ipv4 and needs some checks.  Fixes
   from Isaku Yamahata.

2) Fix sleeps while atomic in netdevice rename code, from Eric Dumazet.

3) Fix double-spinlock in solos-pci driver, from Dan Carpenter.

4) More ARP bug fixes.  Fix lockdep splat in arp_solicit() and then the
   bug accidentally added by that fix.  From Eric Dumazet and Cong Wang.

5) Remove some __dev* annotations that slipped back in, as well as all
   HOTPLUG references.  From Greg KH

6) RDS protocol uses wrong interfaces to access scatter-gather elements,
   causing a regression.  From Mike Marciniszyn.

7) Fix build error in cpts driver, from Richard Cochran.

8) Fix arithmetic in packet scheduler, from Stefan Hasko.

9) Similarly, fix association during calculation of random backoff in
   batman-adv.  From Akinobu Mita.

  IB/rds: suppress incompatible protocol when version is known
  IB/rds: Correct ib_api use with gs_dma_address/sg_dma_len
  net/vxlan: Use the underlying device index when joining/leaving multicast groups
  tcp: should drop incoming frames without ACK flag set

  cpts: fix a run time warn_on.
  cpts: fix build error by removing useless code.
  batman-adv: fix random jitter calculation
  arp: fix a regression in arp_solicit()
  net: sched: integer overflow fix
  CONFIG_HOTPLUG removal from networking core
  Drivers: network: more __dev* removal
  bridge: call br_netpoll_disable in br_add_if
  ipv4: arp: fix a lockdep splat in arp_solicit()
  tuntap: dont use a private kmem_cache
  net: devnet_rename_seq should be a seqcount
  ip_gre: fix possible use after free
  ip_gre: make ipgre_tunnel_xmit() not parse network header as IP unconditionally
  ...

The socket calls from vxlan to join/leave multicast group aren't
using the index of the underlying device, as a result the stack uses
the first interface that is up. This results in vxlan being non functional
over a device which isn't the 1st to be up.
Fix this by providing the iflink field to the vxlan instance
to the multicast calls.

This patch fixes a warning in clk_enable by calling clk_prepare_enable
instead.

The cpts driver tries to obtain the input clock frequency by calling the
clock's internal 'recalc' method. Since <plat/clock.h> has been removed,
this code can no longer compile.

However, the driver never makes use of the frequency value, so this patch
fixes the issue by removing the offending code altogether.

Commit 96442e42429 (tuntap: choose the txq based on rxq)
added a per tun_struct kmem_cache.

As soon as several tun_struct are used, we get an error
because two caches cannot have same name.

Use the default kmalloc()/kfree_rcu(), as it reduce code
size and doesn't have performance impact here.

Retries active opens for INUSE errors.

Logs any active ofld_connect_wr error replies.

Sends ofld_connect_wr on same ctrlq. It needs to go  on the same control txq as
regular CPL active/passive messages.

Retries on active open replies with EADDRINUSE.

Uses active open fw wr only if active filter region is set.

Adds stat for ofld_connect_wr failures.

This patch also adds debugfs file to show endpoints.
