2016-12-02net: ethernet: altera_tse: add support for SGMII PCSNeill Whillans2-0/+102
Add support for the (optional) SGMII PCS functionality of the Altera TSE MAC. If the phy-mode is set to 'sgmii' then we attempt to discover and initialise the PCS so that the MAC can communicate to the PHY. The PCS IP block provides a scratch register for testing presence of the PCS, which is mapped into one of the two MDIO spaces present in the MAC's register space. Once we have determined that the scratch register is functioning, we attempt to initialise the PCS to auto-negotiate an SGMII link with the PHY. There is no need to monitor or manage the SGMII link beyond this, since the normal PHY MDIO will then be used to monitor the media layer. The Altera TSE MAC has only one way in which it can be configured with an SGMII PCS, and as such, this patch only looks to the phy-mode to select whether or not to attempt to initialise the PCS registers. During initialisation, we report the PCS's equivalent of a PHY ID register. This can be parameterised during the IP instantiation and is often left as '0x00000000' which is not an error.

To connect two ports of the same configuration (MDI to MDI or MDI-X to MDI-X) with a 10/100/1000 Mbit/s connection, an Ethernet crossover cable is needed to cross over the transmit and receive signals in the cable, so that they are matched at the connector level. When connecting an MDI port to an MDI-X port a straight through cable is used while to connect two MDI ports or two MDI-X ports a crossover cable must be used. Conventionally MDI is used on end devices while MDI-X is used on hubs and switches Auto MDI-X automatically detects the required cable connection type and configures the connection appropriately, removing the need for crossover cables to interconnect switches or connecting PCs peer-to-peer.

2016-11-30net: ethernet: ti: davinci_cpdma: add set rate for a channelIvan Khoronzhuk2-45/+289
The cpdma has 8 rate limited tx channels. This patch adds ability for cpdma driver to use 8 tx h/w shapers. If at least one channel is not rate limited then it must have higher number, this is because the rate limited channels have to have higher priority then not rate limited channels. The channel priority is set in low-hi direction already, so that when a new channel is added with ethtool and it doesn't have rate yet, it cannot affect on rate limited channels. It can be useful for TSN streams and just in cases when h/w rate limited channels are needed. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S.

Add support for forwarding via XDP. Once the eBPF is attached, driver would allocate & configure a designated transmission queue meant solely for forwarding packets. Said queue would share the receive-queue's interrupt line, and would have it's own Tx statistics. Infrastructure changes required for this [spread-out through the code]: - Determine the DMA direction of the receive buffers based on the presence of the eBPF program. - Turn the sw Tx ring into a union, as regular/XDP queues have different needs for releasing resources after completion [regular requires the SKB, XDP requires the transmitted page].

2016-11-30qed*: Handle-based L2-queues.Mintz, Yuval10-543/+762
The driver needs to maintain several FW/HW-indices for each one of its queues. Currently, that mapping is done by the QED where it uses an rx/tx array of so-called hw-cids, populating them whenever a new queue is opened and clearing them upon destruction of said queues. This maintenance is far from ideal - there's no real reason why QED needs to maintain such a data-structure. It becomes even worse when considering the fact that the PF's queues and its child VFs' queues are all mapped into the same data-structure. As a by-product, the set of parameters an interface needs to supply for queue APIs is non-trivial, and some of the variables in the API structures have different meaning depending on their exact place in the configuration flow. This patch re-organizes the way L2 queues are configured and maintained. In short: - Required parameters for queue init are now well-defined. - Qed would allocate a queue-cid based on parameters. Upon initialization success, it would return a handle to caller. - Queue-handle would be maintained by entity requesting queue-init, not necessarily qed. - All further queue-APIs [update, destroy] would use the opaque handle as reference for the queue instead of various indices. The possible owners of such handles: - PF queues [qede] - complete handles based on provided configuration. - VF queues [qede] - fw-context-less handles, containing only relative information; Only the PF-side would need the absolute indices for configuration, so they're omitted here. - VF queues [qed, PF-side] - complete handles based on VF initialization.

2016-11-30qede: Revise state locking schemeMintz, Yuval3-75/+122
As qede utilizes an internal-reload sequence as result of various configuration changes, the netif state wouldn't always accurately describe the status of the configuration. To compensate, we're storing an internal state of the device, which should only be accessed under the qede_lock. This patch fixes and improves several state/lock interactions: - The internal state should only be checked while locked. - While holding lock, it's preferable to check state rather than the netdevice's state. - The reload sequence is not 'atomic' - unload and subsequent load are not in the same critical section. This also add the 'locked' variant for the reload, which would later be used by XDP - useful in the case where the correct sequence is 'lock, check state and re-configure if good', instead of allowing the reload itself to make the decision regarding the configurability of the device.

Driver's NAPI poll is using a long sequence for processing ingress packets, and it's going to get even longer once we do XDP. Break down the main loop into a series of sub-functions to allow better readability of the function. While we're at it, correct the accounting of the NAPI budget - currently we're counting only packets passed to the stack against the budget, even in case those are actually aggregations.

Currently, the strucutre's fields which are required for datapath related functions [produce/consume] are intertwined with fields which are required only for configuration purposes [init/destroy/etc.]. This patch re-arranges the chain structure so that all the fields which are required for datapath usage could reside in a single cacheline instead of the two which are required today.

Those 2 can safely be united into a single metadata structure. struct qede_agg_info changes the following: /* size: 120, cachelines: 2, members: 9 */ /* sum members: 114, holes: 1, sum holes: 4 */ /* padding: 2 */ /* paddings: 2, sum paddings: 8 */ /* last cacheline: 56 bytes */ --> /* size: 48, cachelines: 1, members: 9 */ /* paddings: 1, sum paddings: 4 */ /* last cacheline: 48 bytes */ Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S.

2016-11-30net: phy: bcm7xxx: Plug in support for reading PHY error countersFlorian Fainelli1-0/+35
Broadcom BCM7xxx internal PHYs can leverage the Broadcom PHY library module PHY error counters helper functions, just implement the appropriate PHY driver function calls to do so. We need to allocate some storage space for our PHY statistics, and provide it to the Broadcom PHY library, so do this in a specific probe function, and slightly wrap the get_stats function call.

2016-11-30net: phy: broadcom: Add support code for reading PHY countersFlorian Fainelli2-0/+75
Broadcom PHYs expose a number of PHY error counters: receive errors, false carrier sense, SerDes BER count, local and remote receive errors. Add support code to allow retrieving these error counters. Since the Broadcom PHY library code is used by several drivers, make it possible for them to specify the storage for the software copy of the statistics.

2016-11-30sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driverEdward Cree44-1220/+18213
Rationale: The differences between Falcon and Siena are in many ways larger than those between Siena and EF10 (despite Siena being nominally "Falcon- architecture"); for instance, Falcon has no MCPU, so there is no MCDI. Removing Falcon support from the sfc driver should simplify the latter, and avoid the possibility of Falcon support being broken by changes to sfc (which are rarely if ever tested on Falcon, it being end-of-lifed hardware). The sfc-falcon driver created in this changeset is essentially a copy of the sfc driver, but with Siena- and EF10-specific code, including MCDI, removed and with the "efx_" identifier prefix changed to "ef4_" (for "EFX 4000- series") to avoid collisions when both drivers are built-in. This changeset removes Falcon from the sfc driver's PCI ID table; then in sfc I've removed obvious Falcon-related code: I removed the Falcon NIC functions, Falcon PHY code, and EFX_REV_FALCON_*, then fixed up everything that referenced them. Also, increment minor version of both drivers (to 4.1). For now, CONFIG_SFC selects CONFIG_SFC_FALCON, so that updating old configs doesn't cause Falcon support to disappear; but that should be undone at some point in the future.
