RDMA/irdma: Introduce GEN3 vPort driver support
In the IPU model, a function can host one or more logical network
endpoints called vPorts. Each vPort may be associated with either a
physical or an internal communication port, and can be RDMA capable. A
vPort features a netdev and, if RDMA capable, must have an associated
ib_dev.
This change introduces a GEN3 auxiliary vPort driver responsible for
registering a verbs device for every RDMA-capable vPort. Additionally,
the UAPI is updated to prevent the binding of GEN3 devices to older
user-space providers.
