v7: Rebase series on top of next-baseband.
v6: Rework total_num_queues in separate commit. Fix typo in comment.
v5: Created separate commit for doc fix. Cosmetic uppercase changes.
v4: Targeting 24.03. Updated FPGA PMD based on review comments.
v3: Made changes requested during review.
v2: Targeting 23.11. Update in commits 1,2 based on review comments.
v1: Targeting 23.07 if possible. Add support for AGX100 (N6000) and corner case fixes.

Looks like this patch was missed.

Maxime, 
I am unsure I get the meaning. Is there anything to be done for this patch?
Thanks

I think it is just a mistake on my side when applying the series, I
don't explain how it happened.

I will pick it for the next release, nothing to do on your side.

Maxime

Hi Hernan,

Could you please rebase and resend this patch that was missed when the
series got applied? I get some conflicts.

Thanks in advance,
Maxime
