Subject: [PATCH v3 net-next 0/8] net/ncsi: Add debugging functionality

This series supports NCSI debugging infrastructure by adding several
debugfs files. 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 debugfs
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.

Changelog
=========
v3:
   * Use pr_debug() instead of pr_warn() upon failure to create
     debugfs directory or file                                       (Joe Perches)
   * Use relative debugfs path/file names in debug messages in
     ncsi-debug.c                                                    (Joe Perches)
   * Use const specifier for @ncsi_pkt_handlers and @ranges          (Joe Perches)
   * Eliminate CONFIG_NET_NCSI_DEBUG ifdef's in *.c                  (Jakub Kicinski)
v2:
   * Use debugfs instead of procfs                                   (Joe Perches)
