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

Pull networking fixes from David Miller:

 1) Clear up some recent tipc regressions because of registration
    ordering. Fix from Junwei Hu.

 2) tipc's TLV_SET() can read past the end of the supplied buffer during
    the copy. From Chris Packham.

 3) ptp example program doesn't match the kernel, from Richard Cochran.

 4) Outgoing message type fix in qrtr, from Bjorn Andersson.

 5) Flow control regression in stmmac, from Tan Tee Min.

 6) Fix inband autonegotiation in phylink, from Russell King.

 7) Fix sk_bound_dev_if handling in rawv6_bind(), from Mike Manning.

 8) Fix usbnet crash after disconnect, from Kloetzke Jan.
