Data Structures For Establishing Multiple Network Profiles Per Each Network Adapter On A Computer System With Heterogeneous Multiple Network Adapters

In a prior art invention, a method of providing a single network configuration for each network adapter using its Media Access Control (MAC) address is described. However, the adapter can have multiple physical link layer interfaces. Although only one physical link layer interface is available at a time, these physical layer interfaces can also be connected to different network servers and gateways. So, it is advantageous to keep multiple network configuration parameters for each existing interface of the adapter. Moreover, it is also desirable to maintain multiple network configurations even though the adapter has only a single interface.

This disclosed method continues the use of the ibm,fw-<mac-addr> property in Non-Volatile Random Access Memory (NVRAM) to store the network parameter information in a profile. A network profile of an adapter is a network configuration which is uniquely identified by a name associated with the adapter. Instead of creating a single network configuration per network adapter and saving it to NVRAM, the new method allows multiple profiles to exist for each network adapter. Hence, each profile created for an adapter can be customized for different network settings. Each profile name is referring to a specific set of network parameters, and an optional description. For example, a network...
