Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull networking tree from David Miller:

1) ptp_pch driver build broke during this merge window due to missing
   slab.h header, fix from Geery Uytterhoeven.

2) If ipset passes in a bogus hash table size we crash because the size
   is not validated properly.  Compounding this, gcc-4.7 can miscompile
   ipset such that even when the user specifies legitimate parameters
   the tool passes in an out-of-range size to the kernel.

   Fix from Jozsef Kadlecsik.

3) Users have reported that the netdev watchdog can trigger with pch_gbe
   devices, and it turns out this is happening because of races in the
   TX path of the driver leading to the transmitter hanging.  Fix from
   Eric Dumazet, reported and tested by Andy Cress.

4) Novatel USB551L devices match the generic class entries for the cdc
   ethernet USB driver, but they don't work because they have generic
   descriptors and thus need FLAG_WWAN to function properly.

   Add the necessary ID table entry to fix this, from Dan Williams.

5) A recursive locking fix in the USBNET driver added a new problem, in
   that packet list traversal is now racy and we can thus access
   unlinked SKBs and crash.

   Avoid this situation by adding some extra state tracking, from Ming
   Lei.

6) The rtlwifi conversion to asynchronous firmware loading is racy, fix
   by reordering the probe procedure.  From Larry Finger.

   Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187

7) Fix regressions with bluetooth keyboards by notifying userland
   properly when the security level changes, from Gustavo Padovan.

8) Bluetooth needs to make sure device connected events are emitted
   before other kinds of events, otherwise userspace will think there is
   no baseband link yet and therefore abort the sockets associated with
   that connection.
