to vmxnet3 device driver. Number of rx queues is limited to 1 in cases
where MSI is not configured or one MSIx vector is not available per rx
queue

It's easier to just annotate the constants as little endian types and set/clear
the flags directly.

Only some netdev feature flags correspond directly to ethtool feature
flags.  ethtool_op_get_flags() does the right thing.

This patch removes config dependency on x86 to build vmxnet3 driver. Thus
the driver can be built on big endian architectures now. Although vmxnet3
is not supported on VMs other than x86 architecture, all this code goes in
to ensure correctness. If the code is not dependent on x86, it should not
assume little endian architecture in any of its operations.
