Merge branch 'mini_cqe' into git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma for-next
Leon Romanovsky says:
====================
Introduce new internal to mlx5 CQE format - mini-CQE. It is a CQE in
compressed form that holds data needed to extra a single full CQE.
It is a stride index, byte count and packet checksum.
====================
* mini_cqe:
IB/mlx5: Introduce a new mini-CQE format
IB/mlx5: Refactor CQE compression response
net/mlx5: Exposing a new mini-CQE format
