People treating the *_pid fields in netlink as a process ID has caused
endless confusion over the years. The fact that our own netlink.h
does this only adds to the confusion.
So here is a patch to change the comments to refer to it as the port
ID which hopefully will make it clear what the purpose of the fields
really is.
