[dpdk-dev] [PATCH 05/22] ixgbe: enlarge the hash flags of RSS to 64 bits

[Helin Zhang <helin.zhang@intel.com>]

As the hash flags of RSS has been enlarged from 16 bits to 64 bits in
'struct rte_eth_rss_conf' in rte_ethdev.h, the size of it in ixgbe should be
enlarged as well. In addition, the flags for ixgbe only should be masked,
as there are flags for others in that 64 bits.
