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.
