Add nettest - a simple program with an implementation for various networking APIs. nettest is used for tcp, udp and raw functional tests for both IPv4 and IPv6. Point of this command versus existing utilities: - controlled implementation of the APIs and the order in which they are called, - ability to verify ingress device, local and remote addresses, - timeout for controlled test length, - ability to discriminate a timeout from a system call failure, and - simplicity with test scripts. The command returns: 0 on success, 1 for any system call failure, and 2 on timeout. Signed-off-by:

Claudiu Manoil says: ==================== enetc: Add mdio bus driver for the PCIe MDIO endpoint First patch fixes a sparse issue and cleans up accessors to avoid casting to __iomem. The second one cleans up the Makefile, to make it easier to add new entries. Third patch just registers the PCIe endpoint device containing the MDIO registers as a standalone MDIO bus driver, to provide an alternative way to control the MDIO bus. The same code used by the ENETC ports (eth controllers) to manage MDIO via local registers applies and is reused. Bindings are provided for the new MDIO node, similarly to ENETC port nodes bindings. Last patch enables the ENETC port 1 and its RGMII PHY on the LS1028A QDS board, where the MDIO muxing configuration relies on the MDIO support provided in the first patch. Changes since v0: v1 - fixed mdio bus allocation v2 - cleaned up accessors to avoid casting v3 - fixed spelling (mostly commit message) v4 - fixed err path check blunder v5 - fixed loadble module build, provided separate kbuild module for the driver ==================== Signed-off-by: -
Claudiu Manoil authored
LS1028a has one Ethernet management interface. On the QDS board, the MDIO signals are multiplexed to either on-board AR8035 PHY device or to 4 PCIe slots allowing for SGMII cards. To enable the Ethernet ENETC Port 1, which can only be connected to a RGMII PHY, the multiplexer needs to be configured to route the MDIO to the AR8035 PHY. The MDIO/MDC routing is controlled by bits 7:4 of FPGA board config register 0x54, and value 0 selects the on-board RGMII PHY. The FPGA board config registers are accessible on the i2c bus, at address 0x66. The PF3 MDIO PCIe integrated endpoint device allows for centralized access to the MDIO bus. Add the corresponding devicetree node and set it to be the MDIO bus parent. Signed-off-by:

The on-chip PCIe root complex that integrates the ENETC ethernet controllers also integrates a PCIe endpoint for the MDIO controller providing for centralized control of the ENETC mdio bus. Add bindings for this "central" MDIO Integrated PCIe Endpoint. Signed-off-by:

Claudiu Manoil authored
ENETC ports can manage the MDIO bus via local register interface. However there's also a centralized way to manage the MDIO bus, via the MDIO PCIe endpoint device integrated by the same root complex that also integrates the ENETC ports (eth controllers). Depending on board design and use case, centralized access to MDIO may be better than using local ENETC port registers. For instance, on the LS1028A QDS board where MDIO muxing is required. Also, the LS1028A on-chip switch doesn't have a local MDIO register interface. The current patch registers the above PCIe endpoint as a separate MDIO bus and provides a driver for it by re-using the code used for local MDIO access. It also allows the ENETC port PHYs to be managed by this driver if the local "mdio" node is missing from the ENETC port node. Signed-off-by:

Clean up overcomplicated makefile to make it more maintainable. Basically, there's a set of common objects shared between the PF and VF driver modules. This can be implemented in a simpler way, without conditionals, less repetition, allowing also for easier updates in the future. Signed-off-by:

What's needed is basically a pointer to the mdio registers. This is one way to store it inside bus->priv allocated space, without upsetting sparse. Reworked accessors to avoid __iomem casting. Used devm_* variant to further clean up the init error / remove paths. Fixes following sparse warning: warning: incorrect type in assignment (different address spaces) expected void *priv got struct enetc_mdio_regs [noderef] <asn:2>*[assigned] regs Fixes: ebfcb23d ("enetc: Add ENETC PF level external MDIO support") Signed-off-by: -

Furthermore, PTP support is added to the MV88E6250 family. v2: - insert all 6220 entries in correct numerical order - introduce invalid_port_mask - move ptp_cc_mult* to ptp_ops and restored original ptp_adjfine code - added Andrews Reviewed-By to patch 2 and 4 ==================== Signed-off-by: -

With this it is possible to mark certain chip ports as invalid. This is required for example for the MV88E6220 (which is in general a MV88E6250 with 7 ports) but the ports 2-4 are not routed to pins. If a user configures an invalid port, an error is returned. Signed-off-by:

Ensures we can talk to a PHY via MDIO on the AST2600, as the MDIO controller is now separate from the MAC. Signed-off-by:

Andrew Jeffery authored
phy-handle is necessary for the AST2600 which separates the MDIO controllers from the MAC. I've tried to minimise the intrusion of supporting the AST2600 to the FTGMAC100 by leaving in place the existing MDIO support for the embedded MDIO interface. The AST2400 and AST2500 continue to be supported this way, as it avoids breaking/reworking existing devicetrees. The AST2600 support by contrast requires the presence of the phy-handle property in the MAC devicetree node to specify the appropriate PHY to associate with the MAC. In the event that someone wants to specify the MDIO bus topology under the MAC node on an AST2400 or AST2500, the current auto-probe approach is done conditional on the absence of an "mdio" child node of the MAC.

The AST2600 design separates the MDIO controllers from the MAC, which is where they were placed in the AST2400 and AST2500. Further, the register interface is reworked again, so now we have three possible different interface implementations, however this driver only supports the interface provided by the AST2600. The AST2400 and AST2500 will continue to be supported by the MDIO support embedded in the FTGMAC100 driver. The hardware supports both C22 and C45 mode, but for the moment only C22 support is implemented. Signed-off-by:

The AST2600 splits out the MDIO bus controller from the MAC into its own IP block and rearranges the register layout. Add a new binding to describe the new hardware. Signed-off-by:

In commit 365ad353 ("tipc: reduce risk of user starvation during link congestion") we allowed senders to add exactly one list of extra buffers to the link backlog queues during link congestion (aka "oversubscription"). However, the criteria for when to stop adding wakeup messages to the input queue when the overload abates is inaccurate, and may cause starvation problems during very high load. Currently, we stop adding wakeup messages after 10 total failed attempts where we find that there is no space left in the backlog queue for a certain importance level. The counter for this is accumulated across all levels, which may lead the algorithm to leave the loop prematurely, although there may still be plenty of space available at some levels. The result is sometimes that messages near the wakeup queue tail are not added to the input queue as they should be. We now introduce a more exact algorithm, where we keep adding wakeup messages to a level as long as the backlog queue has free slots for the corresponding level, and stop at the moment there are no more such slots or when there are no more wakeup messages to dequeue.
