…onfidence usage" This reverts commit 25a84db ("HID: multitouch: enable palm rejection if device implements confidence usage") The commit enables palm rejection for Win8 Precision Touchpad devices but the quirk MT_QUIRK_VALID_IS_CONFIDENCE it is using is not working very properly. This quirk is originally designed for some WIn7 touchscreens. Use of this for a Win8 Precision Touchpad will cause unexpected pointer jumping problem.

The bridge is falsly dropping ipv6 mulitcast packets if there is: 1. No ipv6 address assigned on the brigde. 2. No external mld querier present. 3. The internal querier enabled. When the bridge fails to build mld queries, because it has no ipv6 address, it slilently returns, but keeps the local querier enabled. This specific case causes confusing packet loss. Ipv6 multicast snooping can only work if: a) An external querier is present OR b) The bridge has an ipv6 address an is capable of sending own queries Otherwise it has to forward/flood the ipv6 multicast traffic, because snooping cannot work. This patch fixes the issue by adding a flag to the bridge struct that indicates that there is currently no ipv6 address assinged to the bridge and returns a false state for the local querier in __br_multicast_querier_exists().

The proc connector messages include a sequence number, allowing userspace
programs to detect lost messages. However, performing this detection is
currently more difficult than necessary, since netlink messages can be
delivered to the application out-of-order. To fix this, leave pre-emption
disabled during cn_netlink_send(), and use GFP_NOWAIT.
The following was written as a test case. Building the kernel w/ make -j32
proved a reliable way to generate out-of-order cn_proc messages.

The 3.xx and 4.xx synopsys gmacs have a very similar PCS embedded module and they share almost the same registers: for example: AN_Control, AN_Status, AN_Advertisement, AN_Link_Partner_Ability, AN_Expansion, TBI_Extended_Status. Just the RGMII/SMII Control/Status register differs. So This patch aims to reorganize and enhance the PCS support. It removes the existent support from the dwmac1000/dwmac4_core.c moving basic PCS functions inside a new file called: stmmac_pcs.h. The patch also reviews the available APIs to be better shared among different hardware and easily enhanced to support new features.

The cpsw_suspend() could trigger L3 error and CPSW will stop functioning if System enters suspend when all ethX net-devices are down - in this case CPSW could be already suspended by PM runtime, but cpsw_suspend() will try to call soft_reset_slave() unconditionally and access CPSW registers. Hence, fix it by moving soft_reset_slave() from cpsw_suspend() to cpsw_slave_stop(). This way slave ports will be reset when CPSW is active and will be in proper state during Suspend.

Davinci MDIO is always used as slave device which services read/write requests from MDIO/PHY core. It doesn't use IRQ also. As result, It's possible to relax PM runtime constraints for Davinci MDIO and enable it on demand, instead of powering it during probe and powering off during removal. Hence, implement PM runtime autosuspend for Davinci MDIO, but keep it disabled by default, because Davinci MDIO is integrated in big set of TI devices and not all of them expected to work corectly with RPM autosuspend enabled: - expected to work on SoCs where MDIO is part of TI CPSW (cpsw.c DRA7/am57x, am437x, am335x, dm814x) - not verified on Keystone 2 and other SoCs where MDIO is used with TI EMAC IP (davinci_emac.c: dm6467-emac, am3517-emac, dm816-emac).

Port netdevs (e.g. swXpY) that are not bridged are represented in the device using a vPort with VID=PVID=1 (the PVID vPort), as untagged packets entering the switch are internally tagged with the PVID VLAN. When these packets are routed through a different port netdev they should egress untagged. This wasn't a problem until now, as non-bridged traffic only originated from the CPU, which transmits packets out of the port as-is. When a vPort is created with VID 1 mark it as egress untagged.

When port isn't bridged it is still possible to invoke switchdev ops and configure the device's VLAN filters. However, this will require us to use different Router InterFaces (RIFs) for the same netdev, instead of one per-netdev as with any other configuration. Taking the above into account and the fact that this functionality is questionable with regards to the device's normal use-case, remove it and instead return an error.

When VLAN devices are created on top of LAG, their underlying vPorts are configured correctly with LAG membership. However, the PVID vPort is implicit and already present when the port netdev is put under LAG, so its LAG membership is never set. Set it correctly when joining / leaving LAG. This didn't matter until now, but we are going to introduce support for router interfaces (RIFs), which need to take into account LAG membership.

We are going to assign router interfaces (RIFs) to netdevs if an IPv4 address was assigned to them. If one was assigned to a port netdev, this will translate to the PVID vPort being member in a RIF. While it's possible for a LAG slave to have an IP address, we can't have a vPort being member in two FIDs (assuming the LAG device will be put in bridge / assigned an IP address). Solve that by making the PVID vPort leave any FID it might be a member in when joining / leaving LAG.

During ports initialization a net device is registered for each available port, which implies the port is usable. However, a port is only usable after the different parts of the device (e.g. flooding, buffers) are initialized. This is especially important now, when we must initialize the router before the ports, as otherwise the device can't be initialized. Solve that by initializing the switch ports at the end of init sequence. Also, remove an unnecessary warning about port up/down events, which would otherwise be invoked whenever removing the driver, as ports are removed before unregistering the listener for these events.
