Hi Flip,
I assume that by "port numbers" you mean the PCI bus id (BDF)
that is used by DPDK (for bind, for example).

You can fetch the bus id for a netdevice named "eth0" by
ethtool -i eth0 | grep bus-info
bus-info: 0000:01:00.0

If you mean the internal port number (starting from 0 for the first port, and so on) inside DPDK, then there is no 
mapping between the interface name (as seen by ifconfig) and the internal DPDK port number.

Regards,
Rami  Rosen

Hi,

Is there any mapping between the port names I see while using 'ifconfig'
and the port numbers I use normally to handle NIC ports? In other words, is there a way to identify which ports number corresponds to a given linux interface name?

Thanks
