Some NICs have only one PCI address associated with multiple ports. This
patch extends the dpdk-devargs option's format to cater for such devices.
To achieve that, this patch uses a new syntax that will be adapted and
implemented in future DPDK release (likely, v18.05):
http://dpdk.org/ml/archives/dev/2017-December/084234.html
And since it's the DPDK duty to parse the (complete and full) syntax
and this patch is more likely to serve as an intermediate workaround,
here I take a simpler and shorter syntax from it (note it's allowed to
have only one category being provided):
class=eth,mac=00:11:22:33:44:55:66
Also, old compatibility is kept. Users can still go on with using the
PCI id to add a port (if that's enough for them). Meaning, this patch
will not break anything.
This patch is basically based on the one from Ciara:
