For NGBE devices, the queue number is limited to be 1 when SRIOV is
enabled. In this case, IRQ vector[0] is used for MISC and vector[1] is
used for queue, based on the previous patches. But for the hardware
design, the IRQ vector[1] must be allocated for use by the VF[6] when
the number of VFs is 7. So the IRQ vector[0] should be shared for PF
MISC and QUEUE interrupts.
+-----------+----------------------+
| Vector | Assigned To |
+-----------+----------------------+
| Vector 0 | PF MISC and QUEUE |
| Vector 1 | VF 6 |
| Vector 2 | VF 5 |
| Vector 3 | VF 4 |
| Vector 4 | VF 3 |
| Vector 5 | VF 2 |
| Vector 6 | VF 1 |
| Vector 7 | VF 0 |
+-----------+----------------------+
Minimize code modifications, only adjust the IRQ vector number for this
case.

Most of the different code that requires MAC type in the common library
is due to NGBE only supports a few queues and pools, unlike TXGBE, which
supports 128 queues and 64 pools. This difference accounts for most of
the hardware configuration differences in the driver code. So add a flag
bit "WX_FLAG_MULTI_64_FUNC" for them to clean-up the driver code.

Implement sriov_configure interface for wangxun nics in libwx.
Enable VT mode and initialize vf control structure, when sriov
is enabled. Do not be allowed to disable sriov when vfs are
assigned.
