It was inspired by the reported issues: No available package and channel are probed successfully. Obviously, we don't have a debugging infrastructure for NCSI stack yet. The first 3 patches, fixing some issues, aren't relevant to the subject. I included them because I expect they can be merged beofre the code for debugging infrastructure. PATCH[4,5,6/8] adds procfs directories and files to support the debugging infrastructure for several purposes: presenting the NCSI topology; statistics on sent and received NCSI packets; generate NCSI command packet manually. PATCH[7,8/8] fixes two issues found from the debugging functionality.
