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. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (21 commits) usbnet: fix kernel crash after disconnect selftests: fib_rule_tests: use pre-defined DEV_ADDR net-next: net: Fix typos in ip-sysctl.txt ipv6: Consider sk_bound_dev_if when binding a raw socket to an address net: phylink: ensure inband AN works correctly usbnet: ipheth: fix racing condition net: stmmac: dma channel control register need to be init first net: stmmac: fix ethtool flow control not able to get/set net: qrtr: Fix message type of outgoing packets networking: : fix typos in code comments ptp: Fix example program to match kernel. fddi: fix typos in code comments selftests: fib_rule_tests: enable forwarding before ipv4 from/iif test selftests: fib_rule_tests: fix local IPv4 address typo tipc: Avoid copying bytes beyond the supplied data 2/2] net: xilinx_emaclite: use readx_poll_timeout() in mdio wait function 1/2] net: axienet: use readx_poll_timeout() in mdio wait function vlan: Mark expected switch fall-through macvlan: Mark expected switch fall-through net/mlx4_en: ethtool, Remove unsupported SFP EEPROM high pages query ...
