I am leaning more toward recommending that the topo api be left alone. The topo changes to the ntb api complicate the Intel driver: - The changes add second branches where there had been just one before (need to check topo AND port now). - The changes also cause some complicated merge conflicts with https://github.com/davejiang/linux.git ntb. See RE: [PATCH 10/22] NTB Intel: Add port-related NTB API callback methods If we leave the ntb topo api as it was, then on multiport devices, if the local port is not the primary port, let it be one of potentially many secondary ports. Or, if there is no distinction between primary/secondary on some hardware, let them all be primary. This topo api doesn't have much value for existing drivers (that I know of), except for informative purposes. So, my preference for changing it would be, only if necessary, and to minimize changes otherwise. Allen
