Subject: Add optional support to mxge for MSI-X interrupts and multiple
 receive queues (which we call slices).  The NIC will steer traffic into up to
 hw.mxge.max_slices different receive rings based on a configurable hash type
 (hw.mxge.rss_hash_type).

Currently the driver defaults to using a single slice, so the default
behavior is unchanged.  Also, transmit from non-zero slices is
disabled currently.
