Just for clarification, when you say mem_pools, do you mean vmdq pools?
Also, if you are going to increase MAX_QUEUES, shouldn't you increase the NUM_MBUFS_PER_PORT?
Looking at the comment below, looks like there is a calculation of number of mbufs based on number of queues.
Plus, I assume 128 is the maximum number of queues per port, and as far as I know,
only Fortville supports 256 as maximum.
Thanks,
Pablo
