Hello Max, A question that is not related to the ULP drivers touched by this patch ser= ies: some time ago registration of sg-lists with gaps was disabled in the SRP initiator because arbitrary sg-lists triggered CQE dumps in combination wit= h the mlx5 driver. Does this mean that this issue has been resolved? If so, what = mlx5 driver and/or firmware version are needed to reenable arbitrary sg-list sup= port in the SRP initiator?

Hello Max, A question that is not related to the ULP drivers touched by this patch series: some time ago registration of sg-lists with gaps was disabled in the SRP initiator because arbitrary sg-lists triggered CQE dumps in combination with the mlx5 driver. Does this mean that this issue has been resolved? If so, what mlx5 driver and/or firmware version are needed to reenable arbitrary sg-list support in the SRP initiator? Thanks, Bart.
