cem 06ccf4bc96 Import ioat(4) driver ... I/OAT is also referred to as Crystal Beach DMA and is a Platform Storage Extension (PSE) on some Intel server platforms. This driver currently supports DMA descriptors only and is part of a larger effort to upstream an interconnect between multiple systems using the Non-Transparent Bridge (NTB) PSE. For now, this driver is only built on AMD64 platforms. It may be ported to work on i386 later, if that is desired. The hardware is exclusive to x86. Further documentation on ioat(4), including API documentation and usage, can be found in the new manual page. Bring in a test tool, ioatcontrol(8), in tools/tools/ioat. The test tool is not hooked up to the build and is not intended for end users.
