228 	  MPS (Max Payload Size) and MRRS (Max Read Request Size) are PCIe
232 	  The following choices set the MPS and MRRS optimization strategy
245 	  Use the BIOS defaults; don't touch MPS at all.  This is the same
252 	  Default choice; ensure that the MPS matches upstream bridge.
258 	  Use largest MPS that boot-time devices support.  If you have a

267 	  Use MPS and MRRS for best performance.  Ensure that a given
268 	  device's MPS is no larger than its parent MPS, which allows us to
269 	  keep all switches/bridges to the max MPS supported by their
276 	  Set MPS = 128 for all devices.  MPS configuration effected by the
277 	  other options could cause the MPS on one root port to be
278 	  different than that of the MPS on another, which may cause
279 	  hot-added devices or peer-to-peer DMA to fail.  Set MPS to the
