Pull networking updates from David Miller:
"Highlights:
- Gustavo A. R. Silva keeps working on the implicit switch fallthru
changes.
- Support 802.11ax High-Efficiency wireless in cfg80211 et al, From
Luca Coelho.
- Re-enable ASPM in r8169, from Kai-Heng Feng.
- Add virtual XFRM interfaces, which avoids all of the limitations of
existing IPSEC tunnels. From Steffen Klassert.
- Convert GRO over to use a hash table, so that when we have many
flows active we don't traverse a long list during accumluation.
- Many new self tests for routing, TC, tunnels, etc. Too many
contributors to mention them all, but I'm really happy to keep
seeing this stuff.

| Realtek SMI-based Switches | ||
| ========================== | ||
|
|
||
| The SMI "Simple Management Interface" is a two-wire protocol using | ||
| bit-banged GPIO that while it reuses the MDIO lines MCK and MDIO does | ||
| not use the MDIO protocol. This binding defines how to specify the | ||
| SMI-based Realtek devices. | ||
|
|
||
| Required properties: | ||
|
|
||
| - compatible: must be exactly one of: | ||
| "realtek,rtl8366" | ||
| "realtek,rtl8366rb" (4+1 ports) | ||
| "realtek,rtl8366s" (4+1 ports) | ||
| "realtek,rtl8367" | ||
| "realtek,rtl8367b" | ||
| "realtek,rtl8368s" (8 port) | ||
| "realtek,rtl8369" | ||
| "realtek,rtl8370" (8 port) | ||
|
|
||
| Required properties: | ||
| - mdc-gpios: GPIO line for the MDC clock line. | ||
| - mdio-gpios: GPIO line for the MDIO data line. | ||
| - reset-gpios: GPIO line for the reset signal. | ||
|
|
||
| Optional properties: | ||
| - realtek,disable-leds: if the LED drivers are not used in the | ||
| hardware design this will disable them so they are not turned on | ||
| and wasting power. | ||
|
|
||
| Required subnodes: | ||
|
|
||
| - interrupt-controller | ||
|
|
||
| This defines an interrupt controller with an IRQ line (typically | ||
| a GPIO) that will demultiplex and handle the interrupt from the single | ||
| interrupt line coming out of one of the SMI-based chips. It most | ||
| importantly provides link up/down interrupts to the PHY blocks inside | ||
| the ASIC. | ||
|
|
||
| Required properties of interrupt-controller: | ||
|
|
||
| - interrupt: parent interrupt, see interrupt-controller/interrupts.txt | ||
| - interrupt-controller: see interrupt-controller/interrupts.txt | ||
| - #address-cells: should be <0> | ||
| - #interrupt-cells: should be <1> | ||
|
|
||
| - mdio | ||
|
|
||
| This defines the internal MDIO bus of the SMI device, mostly for the | ||
| purpose of being able to hook the interrupts to the right PHY and | ||
| the right PHY to the corresponding port. | ||
|
|
||
| Required properties of mdio: | ||
|
|
||
| - compatible: should be set to "realtek,smi-mdio" for all SMI devices | ||
|
|
||
| See net/mdio.txt for additional MDIO bus properties. | ||
|
|
||
| See net/dsa/dsa.txt for a list of additional required and optional properties | ||
| and subnodes of DSA switches. | ||
|
|
||
| Examples: | ||
|
|
||
| switch { | ||
| compatible = "realtek,rtl8366rb"; | ||
| /* 22 = MDIO (has input reads), 21 = MDC (clock, output only) */ | ||
| mdc-gpios = <&gpio0 21 GPIO_ACTIVE_HIGH>; | ||
| mdio-gpios = <&gpio0 22 GPIO_ACTIVE_HIGH>; | ||
| reset-gpios = <&gpio0 14 GPIO_ACTIVE_LOW>; | ||
|

| #address-cells = <0>; | ||
| #interrupt-cells = <1>; | ||
