port_type_array Specifies the protocol type of the ports. It is either one array
of 2 port types
't1,t2' for all devices or list of BDF to
port_type_array 'bb:dd.f-t1;t2,...'. (string)
Valid port types: 1-ib, 2-eth, 3-auto, 4-N/A
If only a single port is available, use the N/A port type for
port2 (e.g '1,4').
probe_vf
• If absent or zero: no VF interfaces will be loaded in the
Hypervisor/host
• If num_vfs is a number in the range of 1-63, the driver run-
ning on the Hypervisor will itself activate that number of
VFs. All these VFs will run on the Hypervisor. This number
will apply to all ConnectX® HCAs on that host.
• If its a triplet x,y,z (applies only if all ports are configured
as Ethernet), the driver probes:
• x single port VFs on physical port 1
• y single port VFs on physical port 2 (applies only if such a port
exist)
• z n-port VFs (where n is the number of physical ports on device).
Those VFs are attached to the hypervisor.
• If its format is a string: the string specifies the probe_vf
parameter separately per installed HCA.
The string format is: "bb:dd.f-v,bb:dd.f-v,…
• bb:dd.f = bus:device.function of the PF of the HCA
• v = number of VFs to use in the PF driver for that HCA which is
either a single value or a triplet, as described above
For example:
• probe_vfs=5 - The PF driver will activate 5 VFs on the
HCA and this will be applied to all ConnectX® HCAs on
the host
• probe_vfs=00:04.0-5,00:07.0-8 - The PF driver will
activate 5 VFs on the HCA positioned in BDF 00:04.0 and
8 for the one in 00:07.0)
