For the "most" performance connection, the ULP would use IB, and all these problems go away. :) This proposal is for each iwarp interface to have its own IP address. Clients would need an iwarp usable address of the server and would connect using rdma_connect(). If that call (or rdma_resolve_addr/route) fails, the client could try connecting using sockets, aoi, or some other interface. I don't see that Steve's proposal changes anything from the client's perspective. - Sean - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
