2019-04-16dpaa2-eth: Add flow steering support without maskingIoana Ciocoi Radulescu
On platforms that lack a TCAM (like LS1088A), masking of flow steering keys is not supported. Until now we didn't offer flow steering capabilities at all on these platforms, since our driver implementation configured a "comprehensive" FS key (containing all supported header fields), with masks used to ignore the fields not present in the rules provided by the user. We now allow ethtool rules that share a common key (i.e. have the same header fields). The FS key is now kept in the driver private data and initialized when the first rule is added to an empty table, rather than at probe time. If a rule with a new composition key is wanted, the user must first manually delete all previous rules. When building a FS table entry to pass to firmware, we still use the old building algorithm, which assumes an all-supported-fields key, and later collapse the fields which aren't actually needed. Masked rules are not supported; if provided, the mask value will be ignored. For firmware versions older than MC10.7.0 (that only offer the legacy ABIs for configuring distribution keys) flow steering without masking support remains unavailable.

2019-04-16net: phy: micrel: add Asym Pause workaroundAntoine Tenart
The Micrel KSZ9031 PHY may fail to establish a link when the Asymmetric Pause capability is set. This issue is described in a Silicon Errata (DS80000691D or DS80000692D), which advises to always disable the capability. This patch implements the workaround by defining a KSZ9031 specific get_feature callback to force the Asymmetric Pause capability bit to be cleared. This fixes issues where the link would not come up at boot time, or when the Asym Pause bit was set later on.

2019-04-15Merge branch 'nfp-Flower-flow-merging'David S. Miller
Simon Horman says: ==================== nfp: Flower flow merging John Hurley says, These patches deal with 'implicit recirculation' on the NFP. This is a firmware feature whereby a packet egresses to an 'internal' port meaning that it will recirculate back to the header extract phase with the 'internal' port now marked as its ingress port. This internal port can then be matched on by another rule. This process simulates how OvS datapath outputs to an internal port. The FW traces the packet's recirculation route and sends a 'merge hint' to the driver telling it which flows it matched against. The driver can then decide if these flows can be merged to a single rule and offloaded. The patches deal with the following issues: - assigning/freeing IDs to/from each of these new internal ports - offloading rules that match on internal ports - offloading neighbour table entries whose egress port is internal - handling fallback traffic with an internal port as ingress - using merge hints to create 'faster path' flows and tracking stats etc. ==================== Signed-off-by: David S.

2019-04-15nfp: flower: offload merge flowsJohn Hurley
A merge flow is formed from 2 sub flows. The match fields of the merge are the same as the first sub flow that has formed it, with the actions being a combination of the first and second sub flow. Therefore, a merge flow should replace sub flow 1 when offloaded. Offload valid merge flows by using a new 'flow mod' message type to replace an existing offloaded rule. Track the deletion of sub flows that are linked to a merge flow and revert offloaded merge rules if required.

2019-04-15nfp: flower: support stats update for merge flowsJohn Hurley
With the merging of 2 sub flows, a new 'merge' flow will be created and written to FW. The TC layer is unaware that the merge flow exists and will request stats from the sub flows. Conversely, the FW treats a merge rule the same as any other rule and sends stats updates to the NFP driver. Add links between merge flows and their sub flows. Use these links to pass merge flow stats updates from FW to the underlying sub flows, ensuring TC stats requests are handled correctly. The updating of sub flow stats is done on (the less time critcal) TC stats requests rather than on FW stats update.

2019-04-15nfp: flower: generate merge flow ruleJohn Hurley
When combining 2 sub_flows to a single 'merge flow' (assuming the merge is valid), the merge flow should contain the same match fields as sub_flow 1 with actions derived from a combination of sub_flows 1 and 2. This action list should have all actions from sub_flow 1 with the exception of the output action that triggered the 'implicit recirculation' by sending to an internal port, followed by all actions of sub_flow 2. Any pre-actions in either sub_flow should feature at the start of the action list. Add code to generate a new merge flow and populate the match and actions fields based on the sub_flows.

Rather than increasing the memory requirements of the pre-allocated array, add a new rhashtable to associate each active stats context ID with its rule payload.

Modify the flower app to detect packets from such internal ports and convert the ingress port to the correct kernel space netdev.

Currently, it is assumed that fallback packets will be from reprs. Modify this to allow an app to receive non-repr ports from the fallback channel - e.g. from an internal port. If such a packet is received, do not update repr stats. Change the naming function calls so as not to imply it will always be a repr netdev returned.

2019-04-15nfp: flower: allow offloading of matches on 'internal' portsJohn Hurley
Recent FW modifications allow the offloading of non repr ports. These ports exist internally on the NFP. So if a rule outputs to an 'internal' port, then the packet will recirculate back into the system but will now have this internal port as it's incoming port. These ports are indicated by a specific type field combined with an 8 bit port id. Add private app data to assign additional port ids for use in offloads. Provide functions to lookup or create new ids when a rule attempts to match on an internal netdev - the only internal netdevs currently supported are of type openvswitch. Have a netdev notifier to release port ids on netdev unregister. OvS offloads rules that match on internal ports as TC egress filters. Ensure that such rules are accepted by the driver.

If sk_wmem_schedule() returns false, which means no memory is allowed to allocate, it will block and wait for memory to become available.

2019-04-14r8169: create function pointer array for PHY init functionsHeiner Kallweit
Using a function pointer array makes this easier to read and better maintainable. AFAIK function pointer arrays cause some performance drawback due to Spectre mitigation, but we're not in a hot path here.

2019-04-14net: hns3: free the pending skb when clean RX ringPeng Li
If there is pending skb in RX flow when close the port, and the pending buffer is not cleaned, the new packet will be added to the pending skb when the port opens again, and the first new packet has error data. This patch cleans the pending skb when clean RX ring. Signed-off-by: Peng Li <lipeng321@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2019-04-14net: hns3: do not initialize MDIO bus when PHY is inexistentJian Shen
For some cases, PHY may not be connected to MDIO bus, then the driver will initialize fail since MDIO bus initialization fails. This patch fixes it by skipping the MDIO bus initialization when PHY is inexistent.

2019-04-14net: hns3: set dividual reset level for all RAS and MSI-X errorsWeihang Li
According to hardware description, reset level that should be triggered are not consistent in a module. For example, in SSU common errors, the first two bits has no need to do reset, but the other bits need global reset. This patch sets separate reset level for all RAS and MSI-X interrupts by adding a reset_lvel field in struct hclge_hw_error, and fixes some incorrect reset level.

2019-04-14net: hns3: divide shared buffer between TCYunsheng Lin
Currently hardware may have not enough buffer to receive packet when it has used more than two MPS(maximum packet size) of buffer, but there are still a lot of shared buffer left unused when TC num is small. This patch divides shared buffer to be used between TC when the port supports DCB, and adjusts the waterline and threshold according to user manual for the port that does not support DCB. This patch also change hclge_get_tc_num's return type to u32 to avoid signed-unsigned mix with divide.

2019-04-14net: hns3: always assume no drop TC for performance reasonYunsheng Lin
Currently RX shared buffer' threshold size for speific TC is set to smaller value when the TC's PFC is not enabled, which may cause performance problem because hardware may not have enough hardware buffer when PFC is not enabled. This patch sets the same threshold size for all TC no matter if the specific TC's PFC is enabled.
