The IP address is mapped to a hardware address, typically done using ARP for IPv4, which goes over the ipoib device. The returned hardware address must be in the format defined by the ipoib protocol. That format includes the GID as part of the hardware address. - Sean -- 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
