Author: marius Date: Sun Dec 18 17:48:54 2011 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).
