commit 0c13880cccd75655c878ce31e767bce04b1d6e85 Author: Hans Petter Selasky <[email protected]> AuthorDate: 2021-06-16 13:01:49 +0000 Commit: Hans Petter Selasky <[email protected]> CommitDate: 2021-07-12 12:22:32 +0000 ibcore: Support rate limit for packet pacing Add new member rate_limit to ib_qp_attr which holds the packet pacing rate in kbps, 0 means unlimited. IB_QP_RATE_LIMIT is added to ib_attr_mask and could be used by RAW QPs when changing QP state from RTR to RTS, RTS to RTS.
