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
