That's true - I think I missed updating this commit message when I
realized it. I can correct the commit message while retaining your
Reviewed-by for the v6.

Note: This adds to the confusion I have around the support for
allocating max(rxqs, txqs) config structs; it would seem we'll be
missing config structure for some queues if the system is configured
to use the maximum number of each? Perhaps that configuration is
uncommon enough that it doesn't matter?
