This commit adds the sysfs interface for enabling QP0 on VFs for
selected VF/port.
By default, no VFs are enabled for QP0 operation.
To enable QP0 operation on a VF/port, under
/sys/class/infiniband/mlx4_x/iov/<b:d:f>/ports/x there are two new entries:
- smi_enabled (read-only). Indicates whether smi is currently
enabled for the indicated VF/port
- enable_smi_admin (rw). Used by the admin to request that smi
capability be enabled or disabled for the indicated VF/port.
0 = disable, 1 = enable.
The requested enablement will occur at the next reset of the
VF (e.g. driver restart on the VM which owns the VF).
