[dpdk-dev] [PATCH 06/22] vmxnet3: enlarge the hash flags of RSS to 64 bits

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 vmxnet3 should
be enlarged as well. In addition, the flags for vmxnet3 only should be masked,
as there are flags for others in that 64 bits.
