svn commit: r228694 - head/sys/dev/netmap

New Revision: 228694
URL: http://svn.freebsd.org/changeset/base/228694

Log:
  Fix compilation on sparc64 by actually supplying the bus_dma_tag_t member
  of the rx_ring to bus_dmamap_sync(9). Given that netmap code tries to
  obtain the bus addresses of netmap buffers via vtophys(9) instead of using
  bus_dma(9) it currently has zero chance of actually working on sparc64
  though (and for that matter f.e. also not with MACs limited to 32-bit DMA
  on x86 machines with more than 4GB of RAM).
