Merge branch 'netdev-genl-add-an-xsk-attribute-to-queues'
Joe Damato says:
====================
netdev-genl: Add an xsk attribute to queues
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...
After the RFC [2], Jakub suggested creating an empty nest for queues
which have a pool, so I've adjusted this version to work that way.
The nest can be extended in the future to express attributes about XSK
as needed. Queues which are not used for AF_XDP do not have the xsk
attribute present.
I've run the included test on:
- my mlx5 machine (via NETIF=)
- without setting NETIF
And the test seems to pass in both cases.
