2020-10-11net: mscc: ocelot: offload VLAN mangle action to VCAP IS1Vladimir Oltean2-4/+40
The VCAP_IS1_ACT_VID_REPLACE_ENA action, from the VCAP IS1 ingress TCAM, changes the classified VLAN. We are only exposing this ability for switch ports that are under VLAN aware bridges. This is because in standalone ports mode and under a bridge with vlan_filtering=0, the ocelot driver configures the switch to operate as VLAN-unaware, so the classified VLAN is not derived from the 802.1Q header from the packet, but instead is always equal to the port-based VLAN ID of the ingress port. We _can_ still change the classified VLAN for packets when operating in this mode, but the end result will most likely be a drop, since both the ingress and the egress port need to be members of the modified VLAN. And even if we install the new classified VLAN into the VLAN table of the switch, the result would still not be as expected: we wouldn't see, on the output port, the modified VLAN tag, but the original one, even though the classified VLAN was indeed modified. This is because of how the hardware works: on egress, what is pushed to the frame is a "port tag", which gives us the following options: - Tag all frames with port tag (derived from the classified VLAN) - Tag all frames with port tag, except if the classified VLAN is 0 or equal to the native VLAN of the egress port - No port tag Needless to say, in VLAN-unaware mode we are disabling the port tag. Otherwise, the existing VLAN tag would be ignored, and a second VLAN tag (the port tag), holding the classified VLAN, would be pushed (instead of replacing the existing 802.1Q tag). This is definitely not what the user wanted when installing a "vlan modify" action. So it is simply not worth bothering with VLAN modify rules under other configurations except when the ports are fully VLAN-aware.

2020-10-11enetc: Migrate to PHYLINK and PCS_LYNXClaudiu Manoil7-166/+191
This is a methodical transition of the driver from phylib to phylink, following the guidelines from sfp-phylink.rst. The MAC register configurations based on interface mode were moved from the probing path to the mac_config() hook. MAC enable and disable commands (enabling Rx and Tx paths at MAC level) were also extracted and assigned to their corresponding phylink hooks. As part of the migration to phylink, the serdes configuration from the driver was offloaded to the PCS_LYNX module, introduced in commit 0da4c3d393e4 ("net: phy: add Lynx PCS module"), the PCS_LYNX module being a mandatory component required to make the enetc driver work with phylink.

Move the skb_headroom check out of fr_hard_header and into pvc_xmit. This has two benefits: 1. Originally we only do this check for skbs sent by users on Ethernet- emulating PVC devices. After the change we do this check for skbs sent on normal PVC devices, too. (Also add a comment to make it clear that this is only a protection against upper layers that don't take dev->needed_headroom into account. Such upper layers should be rare and I believe they should be fixed.) 2. After the change we can simplify the parameter list of fr_hard_header. We no longer need to use a pointer to pointers (skb_p) because we no longer need to replace the skb inside fr_hard_header.

2020-10-09ice: refactor devlink_port to be per-VSIJacob Keller5-33/+45
Currently, the devlink_port structure is stored within the ice_pf. This made sense because we create a single devlink_port for each PF. This setup does not mesh with the abstractions in the driver very well, and led to a flow where we accidentally call devlink_port_unregister twice during error cleanup. In particular, if devlink_port_register or devlink_port_unregister are called twice, this leads to a kernel panic. This appears to occur during some possible flows while cleaning up from a failure during driver probe. If register_netdev fails, then we will call devlink_port_unregister in ice_cfg_netdev as it cleans up. Later, we again call devlink_port_unregister since we assume that we must cleanup the port that is associated with the PF structure. This occurs because we cleanup the devlink_port for the main PF even though it was not allocated. We allocated the port within a per-VSI function for managing the main netdev, but did not release the port when cleaning up that VSI, the allocation and destruction are not aligned. Instead of attempting to manage the devlink_port as part of the PF structure, manage it as part of the PF VSI. Doing this has advantages, as we can match the de-allocation of the devlink_port with the unregister_netdev associated with the main PF VSI. Moving the port to the VSI is preferable as it paves the way for handling devlink ports allocated for other purposes such as SR-IOV VFs. Since we're changing up how we allocate the devlink_port, also change the indexing. Originally, we indexed the port using the PF id number. This came from an old goal of sharing a devlink for each physical function. Managing devlink instances across multiple function drivers is not workable. Instead, lets set the port number to the logical port number returned by firmware and set the index using the VSI index (sometimes referred to as VSI handle).

Add "fw.app.bundle_id" to display the DDP Track ID of the active DDP package. This id is similar to "fw.bundle_id" and is a unique identifier for the DDP package that is loaded in the device. Each new DDP has a unique Track ID generated for it, and the ID can be used to identify and track the DDP package. Add documentation for the new devlink info version.

2020-10-09net/rds: suppress page allocation failure error in recv buffer refillManjunath Patil1-3/+3
RDS/IB tries to refill the recv buffer in softirq context using GFP_NOWAIT flag. However alloc failure is handled by queueing a work to refill the recv buffer with GFP_KERNEL flag. This means failure to allocate with GFP_NOWAIT isn't fatal. Do not print the PAF warnings if softirq context fails to refill the recv buffer. We will see the PAF warnings when worker also fails to allocate.

2020-10-09net/mlx5: Add support for devlink reload limit no resetMoshe Shemesh1-0/+25
Add support for devlink reload action fw_activate with reload limit no_reset which does firmware live patching, updating the firmware image without reset, no downtime and no configuration lose. The driver checks if the firmware is capable of handling the pending firmware changes as a live patch. If it is then it triggers firmware live patching flow.

The enable_remote_dev_reset devlink param flags that the host admin allows resets by other hosts. In case it is cleared mlx5 host PF driver will send NACK on pci sync for firmware update reset request and the command will fail. By default enable_remote_dev_reset parameter is true, so pci sync for firmware update reset is enabled.

2020-10-09devlink: Add enable_remote_dev_reset generic parameterMoshe Shemesh3-0/+15
The enable_remote_dev_reset devlink param flags that the host admin allows device resets that can be initiated by other hosts. This parameter is useful for setups where a device is shared by different hosts, such as multi-host setup. Once the user set this parameter to false, the driver should NACK any attempt to reset the device while the driver is loaded.
