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

Pull networking fixes from David Miller:

 1) Include fixes for netrom and dsa (Fabian Frederick and Florian
    Fainelli)

 2) Fix FIXED_PHY support in stmmac, from Giuseppe CAVALLARO.

 3) Several SKB use after free fixes (vxlan, openvswitch, vxlan,
    ip_tunnel, fou), from Li ROngQing.

 4) fec driver PTP support fixes from Luwei Zhou and Nimrod Andy.

 5) Use after free in virtio_net, from Michael S Tsirkin.

 6) Fix flow mask handling for megaflows in openvswitch, from Pravin B
    Shelar.

 7) ISDN gigaset and capi bug fixes from Tilman Schmidt.

 8) Fix route leak in ip_send_unicast_reply(), from Vasily Averin.

 9) Fix two eBPF JIT bugs on x86, from Alexei Starovoitov.

10) TCP_SKB_CB() reorganization caused a few regressions, fixed by Cong
    Wang and Eric Dumazet.

11) Don't overwrite end of SKB when parsing malformed sctp ASCONF
    chunks, from Daniel Borkmann.

12) Don't call sock_kfree_s() with NULL pointers, this function also has
    the side effect of adjusting the socket memory usage.  From Cong Wang.

STMicroelectronics SoC DWMAC glue layer controller
This file documents differences between the core properties in
Documentation/devicetree/bindings/net/stmmac.txt
and what is needed on STi platforms to program the stmmac glue logic.
The device node has following properties.
Required properties:
- compatible : Can be "st,stih415-dwmac", "st,stih416-dwmac" or
"st,stid127-dwmac".
- compatible : Can be "st,stih415-dwmac", "st,stih416-dwmac",
"st,stih407-dwmac", "st,stid127-dwmac".
- reg : Offset of the glue configuration register map in system
configuration regmap pointed by st,syscon property and size.
- reg-names : Should be "sti-ethconf".
- st,syscon : Should be phandle to system configuration node which
encompases this glue registers.
- st,gmac_en: this is to enable the gmac into a dedicated sysctl control
register available on STiH407 SoC.
- sti-ethconf: this is the gmac glue logic register to enable the GMAC,
select among the different modes and program the clk retiming.
- pinctrl-0: pin-control for all the MII mode supported.
- st,tx-retime-src: On STi Parts for Giga bit speeds, 125Mhz clocks can be
wired up in from different sources. One via TXCLK pin and other via CLK_125
pin. This wiring is totally board dependent. However the retiming glue
logic should be configured accordingly. Possible values for this property
"txclk" - if 125Mhz clock is wired up via txclk line.
"clk_125" - if 125Mhz clock is wired up via clk_125 line.
This property is only valid for Giga bit setup( GMII, RGMII), and it is
un-used for non-giga bit (MII and RMII) setups. Also note that internal
clockgen can not generate stable 125Mhz clock.
- st,ext-phyclk: This boolean property indicates who is generating the clock
for tx and rx. This property is only valid for RMII case where the clock can
be generated from the MAC or PHY.
- clock-names: should be "sti-ethclk".
- clocks: Should point to ethernet clockgen which can generate phyclk.
Optional properties:
- resets : phandle pointing to the system reset controller with correct
reset line index for ethernet reset.
- st,ext-phyclk: valid only for RMII where PHY can generate 50MHz clock or
MAC can generate it.
- st,tx-retime-src: This specifies which clk is wired up to the mac for
retimeing tx lines. This is totally board dependent and can take one of the
posssible values from "txclk", "clk_125" or "clkgen".
If not passed, the internal clock will be used by default.
- sti-ethclk: this is the phy clock.
- sti-clkconf: this is an extra sysconfig register, available in new SoCs,
to program the clk retiming.
- st,gmac_en: to enable the GMAC, this only is present in some SoCs; e.g.
STiH407.
Example:
ethernet0: dwmac@fe810000 {
ethernet0: dwmac@9630000 {
device_type = "network";
compatible = "st,stih416-dwmac", "snps,dwmac", "snps,dwmac-3.710";
reg = <0xfe810000 0x8000>, <0x8bc 0x4>;
status = "disabled";
compatible = "st,stih407-dwmac", "snps,dwmac", "snps,dwmac-3.710";
reg = <0x9630000 0x8000>, <0x80 0x4>;

interrupts = <0 133 0>, <0 134 0>, <0 135 0>;
