Hi Just wanted to cross-check with the list on these. Is it always the case that the work requests presented on QP1(mad) shall have only "physical address" owing to the fact that the l_key associated is reserved l_key(or local_dma_key)(from 10.6.4.3.2 of the spec)? But is it mandatory that the consumer shall present memory from reserved l_key on QP1? Is there a use case where normally registered memory(l_key) (and associated virtual address instead of physical) can be used in QP1 work request?
