[AMD Official Use Only - General]

Hi Balakrishnan K,

With respect to error (shared below), I believe this is expected 

```
> [ 1394.034137] uio_pci_generic 0000:06:00.0: No IRQ assigned to device: no 
> support for interrupts?
> [ 1394.037596] uio_pci_generic 0000:06:00.0: No IRQ assigned to device: no 
> support for interrupts?
> [ 1421.498627] uio_pci_generic 0000:06:00.0: No IRQ assigned to device: no

> [ 1421.500976] uio_pci_generic 0000:06:00.0: No IRQ assigned to device: no 
> support for interrupts?
```

Please refer https://doc.dpdk.org/guides/nics/ixgbe.html, section `30.4.5. X550 
does not support legacy interrupt mode`.

With respect to the original error (shared below)

```
>     I am trying to bind VF interface to dpdk using dpdk-devbind.py. Unable to 
> bind getting error ?.
```

As per the IXGBE PMD documentation, one has to follow

```
Step-1: insmod ixgbe.ko MDD=0,0
Step-2: PF port is Kernel driver
Step-3: create VF
Step-4: modprobe vfio `` ``nointxmask=1
Step-5: then bind the VF devices with `vfio-pci`
```

For your question ` cannot bind to driver uio_pci_generic?`, I humbly request 
to check ` The errata is the item #22 from X550 spec update` in section ` 
30.4.5.1. Description`. Then check with Intel Network PMD maintainer if this 
can be fixed.

Note: please do let us know if vfio-pci or igb_uio works for VF devices under 
X540 (as I do not have similar card I unable to test it out for you).
