Sure, no objection here.
My objections are the following (as I said in my previous mail):
- I don't like allocating a 1 KB IU for every send IU, since most of
that memory will probably never be used.
- I'm not convinced that it's _ever_ a win to have the target do
another RDMA to fetch the indirect buffer list. You need to
convince me that it's not better to simply tell the upper layers
what the limit on s/g list length is to fit in the current IU size.
