* | RDMA/ocrdma: Avoid reporting wrong completions in case of error CQEsSelvin Xavier2014-08-01
| | | | | | | | | | | | | | | | | | | | | | | | During cable pull test with a mount over NFS/RDMA, the driver was reporting error completions when there were no pending requests in the SQ and RQ. This was triggering a host crash because of reporting wrong work req id. Avoid this crash by adding a check for SQ and RQ empty condition and prevent reporting completions if queues are empty.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements routine to query the PFC priority from the adapter port. Following are the changes implemented: * A new FW command is implemented to query the operational/admin DCBX configuration from the FW and obtain active priority(service level). * Adds support for the async event reported by FW when the PFC priority changes. Service level is re-initialized during modify_qp or create_ah, based on this event. * Maintain SL value in ocrdma_dev structure and refer that as and when needed.

When dealing with L2 Ethernet, we should use smac, dmac, vlan ID and priority in a similar manner that the IB L2 (and the L4 PKEY) attributes are used. Thus, those attributes were added to the following structures: * ib_ah_attr - added dmac * ib_qp_attr - added smac and vlan_id, (sl remains vlan priority) * ib_wc - added smac, vlan_id * ib_sa_path_rec - added smac, dmac, vlan_id * cm_av - added smac and vlan_id For the path record structure, extra care was taken to avoid the new fields when packing it into wire format, so we don't break the IB CM and SA wire protocol. On the active side, the CM fills. its internal structures from the path provided by the ULP. We add there taking the ETH L2 attributes and placing them into the CM Address Handle (struct cm_av). On the passive side, the CM fills its internal structures from the WC associated with the REQ message. We add there taking the ETH L2 attributes from the WC. When the HW driver provides the required ETH L2 attributes in the WC, they set the IB_WC_WITH_SMAC and IB_WC_WITH_VLAN flags. The IB core code checks for the presence of these flags, and in their absence does address resolution from the ib_init_ah_from_wc() helper function. ib_modify_qp_is_ok is also updated to consider the link layer. Some parameters are mandatory for Ethernet link layer, while they are irrelevant for IB. Vendor drivers are modified to support the new function signature.
