Function rte_bitmap_scan

dpdk/lib/eal/include/rte_bitmap.h:566–583

* Bitmap scan (with automatic wrap-around) * * @param bmp * Handle to bitmap instance * @param pos * When function call returns 1, pos contains the position of the next set * bit, otherwise not modified * @param slab * When function call returns 1, slab contains the value of the entire 64-bit * slab where the bit indicated by pos is located. Slabs are always 64-bit * aligned,

 *   0 if there is no bit set in the bitmap, 1 otherwise
