Logan Gunthorpe a9c59ef774 ntb_test: Add a selftest script for the NTB subsystem ... This script automates testing doorbells, scratchpads and memory windows for an NTB device. It can be run locally, with the NTB looped back to the same host or use SSH to remotely control the second host. In the single host case, the script just needs to be passed two arguments: a PCI ID for each side of the link. In the two host case the -r option must be used to specify the remote hostname (which must be SSH accessible and should probably have ssh-keys exchanged). A sample run looks like this: $ sudo ./ntb_test.sh 0000:03:00.1 0000:83:00.1 -p 29 Starting ntb_tool tests...
