Lots of devices have known good bridges that don't need this limit applied. The MTRON SSD disks are such devices. Transfer rates are increased by 20-30% with the restriction removed. So add a "blacklist" entry for the MTRON devices, with a flag indicating that the bridge is known good. Signed-off-by: Jeff Garzik --- Reading git-diff-tree failed
