206 MPS (Max Payload Size) and MRRS (Max Read Request Size) are PCIe
210 The following choices set the MPS and MRRS optimization strategy
223 Use the BIOS defaults; don't touch MPS at all. This is the same
230 Default choice; ensure that the MPS matches upstream bridge.
236 Use largest MPS that boot-time devices support. If you have a
238 will use the largest MPS that's supported by all devices. This
245 Use MPS and MRRS for best performance. Ensure that a given
246 device's MPS is no larger than its parent MPS, which allows us to
247 keep all switches/bridges to the max MPS supported by their
254 Set MPS = 128 for all devices. MPS configuration effected by the
255 other options could cause the MPS on one root port to be
256 different than that of the MPS on another, which may cause
257 hot-added devices or peer-to-peer DMA to fail. Set MPS to the
