I'm dubious about this. It seems to me like everything (including the
mlx4 low-level driver changes for LSO) would be simpler to implement
and use if we just extend the qp_type to include IB_QPT_UD_LSO. For
example it eliminates the need to test if someone tries to create an
LSO QP for a non-UD transport and return an error (although I don't
see that test in your code anyway).
As I recall, the XRC patches want this flags field too. But does it
work there if we just add another XRC QP type too?
- R.
