[PATCH] net/af_xdp: add rx/tx queue support for af_xdp

[PATCH] net/af_xdp: add rx/tx queue support for af_xdp

[Shivaji Kant]

Driver like GVE do support rx/tx queue configuration
rather than combined queue. Enable AF_XDP vdev to use
rx/tx queue configuration instead of combined queue
configuration if available.

The first sentence is awkward to read.

Is there anything about queues in the driver documentation?

Re: [PATCH v2] net/af_xdp: add rx/tx queue support for af_xdp

[Shivaji Kant]

[-- Attachment #1: Type: text/plain, Size: 5708 bytes --]

Hi Stephen,

Thank you for your review and comments.

Regarding the first sentence of the commit message, you are absolutely
right. I've rephrased it for clarity in v2.

> Is there anything about queues in the driver documentation?

For your question about queues in the driver documentation, the GVE driver
documentation (specifically the
Documentation/networking/device_drivers/google/gve.rst  in the Linux kernel
source) describes the GVE's queue model as having separate RX and TX
queues. While it doesn't explicitly state "combined queues are not
supported," the design clearly indicates a preference for distinct RX and
TX queues, which this patch aims to accommodate for AF_XDP.

I have also corrected the spelling error from "dirvers" to "drivers" in the
code comment.

I've pushed a new version (v2) with these changes. Please let me know if
there are any further issues.

Thanks,
Shivaji
