====================
nfp: devlink, capabilities extensions and updates

This series starts with an improvement to the usability of the device
memory accessors (CPP transactions).  Next few patches are devoted to
fixing the devlink locking.  After recent patches for mlxsw the locking
scheme of devlink ops has to be reworked.  Following patches improve
NFP code dealing with "representors", and expands the error message
printed when driver has no support for loaded FW.

Second part of the series is focused on vNIC capabilities read from
vNIC control memory (often referred to as "BAR0" for historical reasons).
TLV capability format is established and immediately made use of.  The
next patches rework parsing of features for control vNIC which allows
apps to mask out features they don't want enabled.
