Stop abusing xpt_periph in random plases that really have no periph related to CCB, for example, bus scanning. NULL value is fine in such cases and it is correctly logged in debug messages as "noperiph". If at some point we need some real XPT periphs (alike to pmpX now), quite likely they will be per-bus, and not a single global instance as xpt_periph now.

Fix setting of the Rx filters QEMU 1.4 made the descriptor requirement stricter - the size of buffer descriptor must exactly match the number of MAC addresses provided.

have been in production at Netflix for several months with significant success. MFC r246713: Reform the busdma API so that new types may be added without modifying every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. MFC r249538: Some compilers issue a warning when wider integer is casted to narrow pointer. Supposedly shut down the warning by casting through uintptr_t. MFC r251479: Simplify the checking of flags for cam_periph_mapmem(). This gets rid of a lot of code redundancy and grossness at very minor expense. MFC r251837: MFC r251842: Add infrastructure for doing compatibility shims, as has been sorely needed for the last 10 years. Far too much of the internal API is exposed, and every small adjustment causes applications to stop working. To kick this off, bump the API version to 0x17 as should have been done with r246713, but add shims to compensate. Thanks to the shims, there should be no visible change in application behavior.
