[dpdk-dev] [PATCH 20.11 0/5] Enhance rawdev APIs

[Bruce Richardson]

This patchset proposes some internal and externally-visible changes to the
rawdev API. If consensus is in favour, I will submit a deprecation notice
for the changes for the 20.08 release, so that these ABI/API-breaking
changes can be merged in 20.11

The changes are in two areas:
* For any APIs which take a void * parameter for driver-specific structs,
  add an additional parameter to provide the struct length. This allows
  some runtime type-checking, as well as possible ABI-compatibility support
  in the future as structure change generally involve a change in the size
  of the structure.
* Ensure all APIs which can return error values have int type, rather than
  void. Since functions like info_get and queue_default_get can now do some
  typechecking, they need to be modified to allow them to return error
  codes on failure.

Bruce Richardson (5):
  rawdev: add private data length parameter to info fn
  rawdev: allow drivers to return error from info function
  rawdev: add private data length parameter to config fn
  rawdev: add private data length parameter to queue fns
  rawdev: allow queue default config query to return error
