14fe13fcd3 IB/rdmavt: Compress adjacent SGEs in rvt_lkey_ok()
SGEs that are contiguous needlessly consume driver dependent TX resources.

The lkey validation logic is enhanced to compress the SGE that ends
up in the send wqe when consecutive addresses are detected.

The lkey validation API used to return 1 (success) or 0 (fail).

The return value is now an -errno, 0 (compressed), or 1 (uncompressed).  A
additional argument is added to pass the last SQE for the compression.

Loopback callers always pass a NULL to last_sge since the optimization is
of little benefit in that situation.

2a1b7c8b8e IB/rdmavt: Add additional fields to post send trace
This fix is to get additional debugging information.

The following fields are added:
- wqe
- qpt
- num_sge
- ssn
- pid
- send_flags

These additional fields provide for more focused filtering
and triggering.

The patch also moves the trace to just before the wqe is
posted to get the most accurate information and future proofs
the code to trace all possible reserved opcodes.

cf4c2f8c9d IB/rdmavt: Fix trace hierarchy
Split rdmavt traces into separate files to preserve the original
hierarchy since only one trace sub system may now be defined per header
file.
