Logan Gunthorpe ca93c45755 NTB: ntb_pingpong: Choose doorbells based on port number ... This commit fixes pingpong support for existing drivers that do not implement ntb_default_port_number() and ntb_default_peer_port_number(). This is required for hardware (like the crosslink topology of switchtec) which cannot assign reasonable port numbers to each port due to its perfect symmetry. Instead of picking the doorbell to use based on the the index of the peer, we use the peer's port number. This is a bit clearer and easier to understand.
