1196923838 i40iw: Refactor queue depth calculation
Queue depth calculations use a mix of work requests
and actual number of bytes. Consolidate all calculations
using minimum WQE size to avoid confusion.

abae49e433 i40iw: Do not generate CQE for RTR on QP flush
If RTR WQE is posted and QP is flushed, a CQE is
incorrectly generated for the RTR WQE. Add code
to look for the RTR and not generate a CQE when
QP is flushed.

61f51b7b20 i40iw: Set 128B as the only supported RQ WQE size
RQ WQE size other than 128B is not supported.  Correct
RQ size calculation to use 128B only.

Since this breaks ABI, add additional code to
provide compatibility with v4 user provider, libi40iw.

5e58917122 i40iw: Remove macros I40IW_STAG_KEY_FROM_STAG and I40IW_STAG_INDEX_FROM_STAG
The macros I40IW_STAG_KEY_FROM_STAG and I40IW_STAG_INDEX_FROM_STAG are
apparently bad - they are using the logical "&&" operation which
does not make sense here. It should have been a bitwise "&" instead.
Since the macros seem to be completely unused, let's simply remove
them so that nobody accidentially uses them in the future. And while
we're at it, also remove the unused macro I40IW_CREATE_STAG.

85a87c90ee i40iw: Query device accounts for internal rsrc
Some resources are consumed internally and not available to the user.
After hw is initialized, figure out how many resources are consumed
and subtract those numbers from the initial max device capability in
i40iw_query_device().
