cxgbe: fix minimum descriptors requirement Most dpdk examples and apps seem to initialize with a minimum of 128 rx descriptors and 512 tx descriptors for queue setup. However, CXGBE PMD enforces a minimum of 1024 descriptors. This causes the dpdk stack to return -EINVAL because the apps do not request the minimum required. The fix is to relax this enforcing in CXGBE PMD. A minimum of 128 descriptors seems to be a good number with the least impact on the performance.
