2022-02-28RDMA/irdma: Fix Passthrough mode in VMMustafa Ismail1-0/+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.

2021-09-20RDMA/irdma: Skip CQP ring during a resetSindhu Devale1-1/+1
Due to duplicate reset flags, CQP commands are processed during reset. This leads CQP failures such as below: irdma0: [Delete Local MAC Entry Cmd Error][op_code=49] status=-27 waiting=1 completion_err=0 maj=0x0 min=0x0 Remove the redundant flag and set the correct reset flag so CPQ is paused during reset Fixes: 8498a30e1b94 ("RDMA/irdma: Register auxiliary driver and implement private channel OPs") Link: https://lore.kernel.org/r/20210916191222.824-2-shiraz.saleem@intel.com Reported-by: LiLiang <liali@redhat.com> Signed-off-by: Sindhu Devale <sindhu.devale@intel.com> Signed-off-by: Shiraz Saleem <shiraz.saleem@intel.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
