[PATCH v3 net-next 0/5] ionic bits and bytes

[PATCH v3 net-next 0/5] ionic bits and bytes

[Shannon Nelson]

These are a few little updates to the ionic driver while we are in between
other feature work.  While these are mostly Fixes, they are almost all low
priority and needn't be promoted to net.  The one higher need is patch 1,
but it is fixing something that hasn't made it out of net-next yet.

v3: allow decode of unknown transciever and use type
    codes from sfp.h
v2: add Fixes tags to patches 1-4, and a little
    description for patch 5

Shannon Nelson (5):
  ionic: stop devlink warn on mgmt device
  ionic: deinit rss only if selected
  ionic: remove adminq napi instance
  ionic: print data for unknown xcvr type
  ionic: add decode for IONIC_RC_ENOSUPP

[PATCH v3 net-next 1/5] ionic: stop devlink warn on mgmt device

[Shannon Nelson]

If we don't set a port type, the devlink code will eventually
print a WARN in the kernel log.  Because the mgmt device is
not really a useful port, don't register it as a devlink port.

[PATCH v3 net-next 4/5] ionic: print data for unknown xcvr type

[Shannon Nelson]

If we don't recognize the transceiver type, set the xcvr type
and data length such that ethtool can at least print the first
256 bytes and the reader can figure out why the transceiver
is not recognized.

While we're here, we can update the phy_id type values to use
the enum values in sfp.h.
