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

285 	  Use MPS and MRRS for best performance.  Ensure that a given
286 	  device's MPS is no larger than its parent MPS, which allows us to
287 	  keep all switches/bridges to the max MPS supported by their

295 	  other options could cause the MPS on one root port to be
296 	  different than that of the MPS on another, which may cause
