Cover letter [PATCH rdma-next 0/3] Packet based credit mode
From: Leon Romanovsky <[email protected]>
Quoted 1 line
From Danit,
Packet based credit mode is an alternative end-to-end credit mode for QPs set during their creation. Credits are transported from the responder to the requester to optimize the use of its receive resources. In packet-based credit mode, credits are issued on a per packet basis.
The advantage of this feature comes while sending large RDMA messages through switches that are short in memory.
The first commit exposes QP creation flag and the HCA capability. The second commit adds support for a new DV QP creation flag. The last commit report packet based credit mode capability via the MLX5DV device capabilities.
Thanks
