Which property can help to distinguish Napatech ports?
Can you use class=3Deth,dev_port=3DX ?
The dev_port property will use /sys/class/net/DEV/dev_port on Linux. Is=
it
OK for you?
Actually, what we were thinking of was using the mac property in the class=
=20
category to distinguish our ports.
For instance:=20
-w bus=3Dpci,id=3D0000:01:00.0/class=3Deth,mac=3D00:11:22:33:44:55
or simply:
-w class=3Deth,mac=3D00:11:22:33:44:55
We will not be able to support the dev_port property, that will not work fo=
r us.
At least not for now.

Finn
