[dpdk-dev] [PATCH v2] tools/dpdk_nic_bind: Fix can't bind virtio-pci issue

[Thomas Monjalon]

> > The dpdk_nic_bind script will not allow ports to be bound or unbound if none of the
> > kernel modules supported by DPDK is loaded. This patch relaxes this restriction by
> > checking if a DPDK module is actually requested. The example below illustrates this
> > problem:
> >
> > In virtio test, on the guest
> > 1. Bind virtio port to igb_uio driver;
> > 2. Remove igb_uio module;
> > 3. Bind virtio port to virtio-pci driver, it fails and reports:
> >    "Error - no supported modules are loaded"
> >
> > The script should check the to-be-bound driver flag, if it is dpdk driver(igb_uio, vfio etc),
> > and the corresponding module is not loaded, then exit, otherwise, just report a warning,
> > and continue to bind the non-dpdk driver(like virtio-pci) to dev.
