Subject: [PATCH net-next 00/10] nfp: enhanced debug dump via ethtool

Add debug dump implementation to the NFP driver. This makes use of
existing ethtool infrastructure.  ethtool -W is used to select the dump
level and ethtool -w is used to dump NFP state.

The existing behaviour of dump level 0, dumping the arm.diag resource, is
preserved. Dump levels greater than 0 are implemented by this patchset and
optionally supported by firmware providing a _abi_dump_spec rtsym. This
rtsym provides a specification, in TLV format, of the information to be
dumped from the NFP at each supported dump level.

Dumps are also structured using a TLVs. They consist a prolog and the data
described int he corresponding dump.

Carl Heymann (10):
  nfp: debug dump ethtool ops
  nfp: load debug dump spec
  nfp: dump prolog
  nfp: dumpspec TLV traversal
  nfp: dump rtsyms
  nfp: dump all hwinfo
  nfp: dump single hwinfo field by key
  nfp: dump firmware name
  nfp: dump CPP, XPB and direct ME CSRs
  nfp: dump indirect ME CSRs
