We discussed MDT support in GLDv3 in the context that Nicolas was trying to see what options we have if non-fastpath performance result does not turn out well. But if we can prove the new-fast-path works out okay, I don't think we will add MDT to GLDv3 which will soon be pulled out when the new fast-path code is in. >> I do recall a separate discussion that the >> new fastpath should be able to use MDT, but I don't think it needs >> MAC_CAPAB_LDT to do so. >> That is correct.
