From: Dave Jiang <[email protected]> Currently the debugfs does not have files for all NTB transport queue pairs. When there are multiple NTBs present in a system, the QP names of the last transport clobber the names of previously added transport QPs. Only the last added QPs can be observed via debugfs.
Create a directory per NTB transport to associate the QPs with that transport. Name the directory the same as the PCI device.
