| | | | | | | | | | | | | | | | | | | | | | The driver has a check to ensure that NCSI FW section is updated only if the current FW version in the card supports it. This FW version check is done using memcmp() which obviously fails in some cases. Fix this by breaking up the version string into integer version components and comparing them.

| * be2net: Provide an alternate way to read pf_num for BEx chipsSriharsha Basavapatna2016-10-092-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | The driver gets the pf_num for Skyhawk and Lancer using GET_FUNC_CONFIG FW command. But since that command is not supported in BEx, we need to get it from some other command. Otherwise TPE recovery would fail since all NIC PFs would end up with a func num of 0. There's a pci function number field in the response of GET_CNTL_ATTRIBUTES command that can be read to get the same info for BEx adapters.

| * xen-netback: make sure that hashes are not send to unaware frontendsPaul Durrant2016-10-071-11/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case when a frontend only negotiates a single queue with xen- netback it is possible for a skbuff with a s/w hash to result in a hash extra_info segment being sent to the frontend even when no hash algorithm has been configured. (The ndo_select_queue() entry point makes sure the hash is not set if no algorithm is configured, but this entry point is not called when there is only a single queue). This can result in a frontend that is unable to handle extra_info segments being given such a segment, causing it to crash. This patch fixes the problem by clearing the hash in ndo_start_xmit() instead, which is clearly guaranteed to be called irrespective of the number of queues.

| * xen-netback: retire guest rx side prefix GSO featurePaul Durrant2016-10-064-50/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As far as I am aware only very old Windows network frontends make use of this style of passing GSO packets from backend to frontend. These frontends can easily be replaced by the freely available Xen Project Windows PV network frontend, which uses the 'default' mechanism for passing GSO packets, which is also used by all Linux frontends. NOTE: Removal of this feature will not cause breakage in old Windows frontends. They simply will no longer receive GSO packets - the packets instead being fragmented in the backend.

Summary: - updates to mlx5 - updates to mlx4 (two conflicts, both minor and easily resolved) - updates to iw_cxgb4 (one conflict, not so obvious to resolve, proper resolution is to keep the code in cxgb4_main.c as it is in Linus' tree as attach_uld was refactored and moved into cxgb4_uld.c) - improvements to uAPI (moved vendor specific API elements to uAPI area) - add hns-roce driver and hns and hns-roce ACPI reset support - conversion of all rdma code away from deprecated create_singlethread_workqueue - security improvement: remove unsafe ib_get_dma_mr (breaks lustre in staging)" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (75 commits) staging/lustre: Disable InfiniBand support iw_cxgb4: add fast-path for small REG_MR operations cxgb4: advertise support for FR_NSMR_TPTE_WR IB/core: correctly handle rdma_rw_init_mrs() failure IB/srp: Fix infinite loop when FMR sg[0].offset != 0 IB/srp: Remove an unused argument IB/core: Improve ib_map_mr_sg() documentation IB/mlx4: Fix possible vl/sl field mismatch in LRH header in QP1 packets IB/mthca: Move user vendor structures IB/nes: Move user vendor structures IB/ocrdma: Move user vendor structures IB/mlx4: Move user vendor structures IB/cxgb4: Move user vendor structures IB/cxgb3: Move user vendor structures IB/mlx5: Move and decouple user vendor structures IB/{core,hw}: Add constant for node_desc ipoib: Make ipoib_warn ratelimited IB/mlx4/alias_GUID: Remove deprecated create_singlethread_workqueue IB/ipoib_verbs: Remove deprecated create_singlethread_workqueue IB/ipoib: Remove deprecated create_singlethread_workqueue ...

This avoids FW having to do an async read of the TPTE blocking the SQ until the read completes. To know if the current MR state is INVALID or not, iw_cxgb4 must track the state of each fastreg MR. The c4iw_mr struct state is updated as REG_MR and LOCAL_INV WRs are posted and completed, when a reg_mr is destroyed, and when RECV completions are processed that include a local invalidation. This optimization increases small IO IOPS for both iSER and NVMF. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

| * | | | | IB/mlx4: Fix possible vl/sl field mismatch in LRH header in QP1 packetsJack Morgenstein2016-10-071-4/+9

When building a QP1 packet, the VL field should reflect the SLtoVL mapping and not arbitrarily contain zero (as is done now). This bug causes credit problems in IB switches at high rates of QP1 packets. The fix is to cache the SL to VL mapping in the driver, and look up the VL mapped to the SL provided in the send request when sending QP1 packets. For FW versions which support generating a port_management_config_change event with subtype sl-to-vl-table-change, the driver uses that event to update its sl-to-vl mapping cache. Otherwise, the driver snoops incoming SMP mads to update the cache. There remains the case where the FW is running in secure-host mode (so no QP0 packets are delivered to the driver), and the FW does not generate the sl2vl mapping change event. To support this case, the driver updates (via querying the FW) its sl2vl mapping cache when running in secure-host mode when it receives either a Port Up event or a client-reregister event (where the port is still up, but there may have been an opensm failover). OpenSM modifies the sl2vl mapping before Port Up and Client-reregister events occur, so if there is a mapping change the driver's cache will be properly updated.

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>.
