The IBTA specifically does not define software interfaces. The concern here is the architecture and definition of the linux rdma software stack, not verbs, despite the fact that the layer is named that. > As I said earlier, the network layer (e.g., IPv4, IPv6, or GRH) cannot be > a port attribute because RoCE HCAs support all of them over the same > physical port. IMO, the architecture needs to change to support multiple network and transport layers over the same link layer. The current restriction of 1 "transport" per port is too restrictive, and doesn't seem to be true even for current devices, like usnic. > Maybe we should change these patches to encode the port "summary" as a bit > mask, and provide convenient masks for queries? Switching to bit masks is the longer term objective. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
