2020-08-18RDMA/efa: Introduce SRD RNR retryGal Pressman1-6/+11
This patch introduces the ability to configure SRD QPs with the RNR retry parameter when issuing a modify QP command. In addition, a capability bit was added to report support to the userspace library.

2020-05-21RDMA/efa: Report host information to the deviceGal Pressman1-1/+62
The host info feature allows the driver to infrom the EFA device firmware with system configuration for debugging and troubleshooting purposes. The host info buffer is passed as an admin command DMA mapped control buffer, and is unmapped and freed once the command CQE is consumed. Currently, the setting of host info is done for each device on its probe. Failing to set the host info for the device shall not disturb the probe flow, any errors will be discarded.

2019-05-06RDMA/efa: Add EFA device definitionsGal Pressman1-0/+794
EFA PCIe device implements a single Admin Queue (AQ) and Admin Completion Queue (ACQ) pair to initialize and communicate configuration with the device. Through this pair, we run set/get commands for querying and configuring the device, create/modify/destroy queues, and IB specific commands like Address Handler (AH), Memory Registration (MR) and Protection Domains (PD). In addition to admin (AQ/ACQ), we have data path queues that get classified as Queue Pairs (QP) and Completion Queues (CQ).
