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.

net/cxgbe: support updating RSS hash configuration and key Add firmware API for updating RSS hash configuration and key. Move RSS hash configuration from cxgb4_write_rss() to a separate function cxgbe_write_rss_conf(). Also, rename cxgb4_write_rss() to cxgbe_write_rss() for consistency.
