How about this:

    net/bnxt: increase max burst size for vector mode

    Increase the maximum supported burst size for the bnxt vector
    mode PMD from 32 to 64. With larger burst sizes, per-burst
    overhead is amortized over more packets, improving overall
    performance. For small packets this has been measured to
    provide a 4-10% increase in single-core throughput with
    testpmd iofwd.

Thanks,
    Lance
