Aggregated Ethernet-specific naming for logical systems

Aggregated Ethernet interfaces created under a logical system can be individually named. Prior to this release, aggregated Ethernet interfaces were named automatically, AE1, AE2, and so on, upon setting the device count, and system resources were allocated for each aggregated Ethernet interface regardless of whether it was used or not. This change allows administrators to use whatever naming scheme makes sense in the context of their deployment and is more efficient in the allocation of system resources.
