[dpdk-dev] [PATCH v2 08/27] vmxnet3: enlarge the hash flags of RSS to 64 bits

[Helin Zhang]

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