This series is a continuous improvement for the uverbs
extension mechanism and flow steering uverbs that were
introduced as an experimental features for v3.12.
I suggested and implemented the following improvements:
- improved extensible/extended command infrastructure
with clear split between core/ (eg. uverbs) and hw/ (eg. provider)
portion of command and response;
- structure renaming to match others uverbs public structs;
- changes usage of the flow_attr.size to not count the
"extended command header" but to describe only the size
of the flow specs following flow_attr;
- removed unneeded flow_spec structure that don't need to be
exposed to userspace.
- ensure 64bits alignment
Changes from v1 (patchset [1]):
- re-enable patch by Matan Barack as the last step
- patch moving comp_mask in command header dropped following
discussion about having comp_mask for provider data and response.
- moved variable written_count in an inner block
Changes from v0 (patchset [2]):
- Re-enable flow steering verbs and the extension verbs mechanism.
- Squashed patches 1 and 2 from the original series
- ib_uverbs_write should return the number of bytes including the
header's size (Patch 7).
Changes from v(-1) (patchset [3] and patchset [4]):
- merge infrastructure and uverbs flow fixes
- rebased against Matan Barack fixes
- removed changes on function name
Changes from initial (patchset [5]):
- move "comp_mask" in the command header
- add a response header
- add strict command length check
