Hi,
I see that with commit 021c1f24f002 ("RDMA/mlx5: Support SQD2RTS for modify QP"), the driver supports the SQD -> RTS transition. Which is good.
But I see no way how the driver can transition a QP into SQD in the first place. Is the RTS -> SQD transition missing?
Thxs, Håkon

I see this callchain:
__mlx5_ib_modify_qp ->
mlx5_core_qp_modify ->
modify_qp_mbox_alloc
mlx5_cmd_exec
Thanks

I cannot find SQD i optab, so how can RTS -> SQD be supported?
