In the latest IB core version, it has some known issues with memory registration using the local_dma_lkey. Thus RoCE don't expose support for it, and remove device->local_dma_lkey which is introduced to working systems. Signed-off-by:

According to the Infiniband spec, NodeGUID uniquely identifies a node. This must be initialized to some unique value. This patch adds the support to the HNS RoCE driver to fetch the NodeGUID value from DT or ACPI and then use this value to initialize the node_guid parameter of IB device. This value shall be used by RDMA CM. Signed-off-by:

This patch adds get_netdev() function to the IB device. This shall be used to fetch netdev corresponding to the port number. This function would be called by IB core(Generic CM Agent) for example, when the RDMA connection is being established. Signed-off-by:

When the dsaf mode receives a broadcast packet, it will filter the packet by comparing the received queue number and destination queue number(get from forwarding table), if they are the same, the packet will be filtered. Otherwise, the packet will be loopback. So this patch select queue 0 to send broadcast and multicast packets. Signed-off-by:

As the sub queue id in the broadcast forwarding table is always set to absolute queue 0 rather than the interface's relative queue 0, this will cause the received broadcast packets loopback to rcb. This patch sets the sub queue id to relative queue 0 of each port. Signed-off-by:

After running command "ethtool -t eth0", eth0 can not be connected to network. It is caused by the changing the inner loopback register and this register cannot be changed when hns connected to network. The routine of setting this register needs to be removed and using promisc mode to let the packet looped back pass by dsaf mode. Reported-by:

This patch is meant to add support of ACPI to the Hisilicon RoCE driver. Changes done are primarily meant to detect the type and then either use DT specific or ACPI spcific functions. Where ever possible, this patch tries to make use of Unified Device Property Interface APIs to support both DT and ACPI through single interface. This patch depends upon HNS ethernet driver to Reset RoCE. This function within HNS ethernet driver has also been enhanced to support ACPI and is part of other accompanying patch with this patch-set. NOTE: The changes in this patch are done over below branch, https://github.com/dledford/linux/tree/hns-roceSigned-off-by:

In the Hip06 SoC, the RoCE Engine is part of the Hisilicon Network Subsystem and is dependent upon DSAF module. Therefore, certain functions like RESET are exposed through the common registers of HNS DSAF module which are memory-mapped by the HNS driver and currently can only be accessed through DT/syscon interface. This patch adds the support of ACPI to the existing RoCE reset function in the HNS driver(please refer NOTE 2). Hisilicon RoCE driver (please refer NOTE 1) shall call this reset function during probe time to reset the RoCE Engine. The HNS Reset function indirectly ends up in calling the _DSM() function part of the DSDT ACPI Table. Actual reset functionality for ACPI is implemented within the ACPI DSDT Table which also has been enhanced to support this change. Support of ACPI in the HNS RoCE driver shall be pushed through a different accompanying below patch: "IB/hns: Add support of ACPI to the Hisilicon RoCE Driver" NOTE 1: HNS RoCE driver has already been accepted by its maintainer Doug Ledford<dledford@redhat.com>. Please refer below link: https://www.spinics.net/lists/linux-rdma/msg38850.html NOTE 2: RoCE reset function patch has been accepted and now is part of the net-next: https://www.mail-archive.com/netdev@vger.kernel.org/msg123867.htmlSigned-off-by:

Veola fixes how the backplane reports the media in ethtool, as KR, KX or KX4 based on the backplane interface present. Emil fixes ixgbevf since an incorrect size parameter for ixgbevf_write_msg_read_ack() ended up only giving the PF the first 4 bytes of the MAC address, so correct the size by calculating it on the fly for all instances where we call ixgbevf_write_msg_read_ack().

Add geneve Rx offload support for x550em_a. The implementation follows the vxlan code with the lower 16 bits of the VXLANCTRL register holding the UDP port for VXLAN and the upper for Geneve. Disabled NFS filters in the RFCTL register which allows us to simplify the check for VXLAN and Geneve packets in ixgbe_rx_checksum(). Removed vxlan from the name of the callback functions and replaced it with udp_tunnel which is more in line with the new API. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-08-19 This series contains updates to i40e and i40evf only. Jake provides several patches, first just moves a function to co-locate the two functions related to configuring RSS via the admin queue, which should help in spotting bugs when comparing the two functions. Fixed an issue where commit e69ff813 ("i40e: rework the functions to configure RSS with similar parameters") missed checking whether the seed is NULL before using it and did not use the passed in *lut parameter. Fixed an issue where a previous refactor missed i40e_vsi_config_rss() and the values were being ignored, so checked for the fields and used them instead of default values. Lastly replaced calls to create_singlethread_workqueue() with alloc_workqueue() to provide more control over workqueue creation and allows explicit setting of the desired mode of operation. Mitch adds link speed to log messages and reports speed through ethtool. Carolyn refactors tail bump check and fixes byte ordering problems found when enabling this feature support. Adds support for HMC resources and profile commands for x722 firmware. Heinrich Schuchardt fixes format identifiers from %u to %d since the variable is defined as an integer. Catherine fixes an issue where there was a race condition between the completion of the client open and calls to the client ops, so ensured that client ops are not called until we are sure client is open. Harshitha makes sure that i40e_client_release() does not try to use an adapter pointer which may not be initialized, so make sure it is. Joe Perches fixes the use of the local macro XSTRINGIFY() to use __stringify() instead. Avinash corrects the mutex usage in client_subtask(). Fixed the RDMA client to open again after reset since it is closed during a PF reset. Jeff (me) clean up whitespace issues, where indentation was done inconsistently and with spaces versus tabs. ==================== Signed-off-by:

The patch creates sample code exercising bpf_skb_{set,get}_tunnel_key, and bpf_skb_{set,get}_tunnel_opt for GRE, VXLAN, and GENEVE. A native tunnel device is created in a namespace to interact with a lwtunnel device out of the namespace, with metadata enabled. The bpf_skb_set_* program is attached to tc egress and bpf_skb_get_* is attached to egress qdisc. A ping between two tunnels is used to verify correctness and the result of bpf_skb_get_* printed by bpf_trace_printk. Signed-off-by:William Tu <u9012063@gmail.com> Signed-off-by:

The existing code uses busy retry when unable to send out receive completions due to full ring buffer. It also gives up retrying after limit is reached, and causes receive buffer slots not being recycled. This patch implements batching of receive completions. It also prevents dropping receive completions due to full ring buffer. Signed-off-by:

Correcting the mutex usage, in client_subtask(), mutex_unlock has to be called just before client_del_instance() since this function opens and later closes the same mutex again. Similarly in client_is_registered removing the mutex since it closes the mutex twice. This is a patch suggested by RDMA team. Change-ID: Icce519c266e4221b8a2a72a15ba5bf01750e5852 Signed-off-by:
