This series supports NCSI debugging infrastructure by adding several
ethtool commands and one debugfs file. 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[4,5,6,7] adds ethtool
commands to dump NCSI topology, channel information, HW statistics
and SW statistics. PATCH[8] adds debugfs entry /sys/kernel/debug/
ncsi/eth0/pkt, which sends NCSI command packet on write. The NCSI
response packet are dumped on read. PATCH[9,10] fix two issues
found by the debugging functionality.
