Greetings:
This is an attempt to followup on something Jakub asked me about [1], adding an xsk attribute to queues and more clearly documenting which queues are linked to NAPIs...
But:
1. I couldn't pick a good "thing" to expose as "xsk", so I chose 0 or 1. Happy to take suggestions on what might be better to expose for the xsk queue attribute.
2. I create a silly C helper program to create an XDP socket in order to add a new test to queues.py. I'm not particularly good at python programming, so there's probably a better way to do this. Notably, python does not seem to have a socket.AF_XDP, so I needed the C helper to make a socket and bind it to a queue to perform the test.
Tested this on my mlx5 machine and the test seems to pass.
Happy to take any suggestions / feedback on this one; sorry in advance if I missed many obvious better ways to do things.
Thanks, Joe
