* RDMA/irdma: Add wait for suspend on SQDMustafa Ismail2023-11-151-1/+1
| | | | | | | | | | | | | Currently, there is no wait for the QP suspend to complete on a modify to SQD state. Add a wait, after the modify to SQD state, for the Suspend Complete AE. While we are at it, update the suspend timeout value in irdma_prep_tc_change to use IRDMA_EVENT_TIMEOUT_MS too.

* IB: Use capital "OR" for multiple licenses in SPDXKrzysztof Kozlowski2023-09-111-1/+1
| | | | | | | | | | Documentation/process/license-rules.rst and checkpatch expect the SPDX identifier syntax for multiple licenses to use capital "OR". Correct it to keep consistent format and avoid copy-paste issues.

* RDMA/irdma: Add support for address handle re-useMustafa Ismail2022-03-151-1/+1
| | | | | | | | | | | Address handles (AH) are a limited HW resource and some user applications may create large numbers of identical AH's. Avoid running out of AH's by reusing existing identical ones.

* RDMA/irdma: Fix Passthrough mode in VMMustafa Ismail2022-02-281-0/+1
| | | | | | | | | | | | | | | Using PCI_FUNC macro in a VM, when the device is in passthrough mode does not provide the real function instance. This means that currently, devices will not probe unless the instance in the VM matches the instance in the host. Fix this by getting the pf_id from the LAN during the probe.
