1. Added module parameters sr_iov and probe_vf for controlling enablement of
SRIOV mode.
This sort of option is useful in many drivers, and ideally would be
specified in some generic way rather than a module parameters. However
I can't see a good way to make it configurable after the

The 'probe_vf' parameter is very odd. Why do you think it is necessary
to make this a module parameter? It should be possible to bind and
unbind the driver from each VF dynamically via sysfs but this parameter
appears to restrict that.

Currently, we abort the device startup. I can change this to simply continue
without sriov enabled:
Agree... we definitely don't want

I don't think it's a good idea to put module parameters inside an

Jack,
If CONFIG_PCI_IOV isn't set, pci_enable_sriov isn't there...
Or.

Not so. I checked. If CONFIG_PCI_IOV

Not so. I checked. If CONFIG_PCI_IOV isn't set, pci_enable_sriov returns
-ENODEV via a static inline function. Look in kernel file include/linux/pci.h
(for the most recent kernel)

1. Added module parameters sr_iov and probe_vf for controlling enablement of
SRIOV mode.
2. Increased default max num-qps, num-mpts and log_num_macs to accomodate
SRIOV mode
3. Added port_type_array as a module parameter to allow driver
