Remove HMC network restriction that 2nd NIC must be in a separate network

The current HMC network setup requires that the 2nd NIC on an HMC be in a separate network. The restriction should be removed, so the 2nd NIC can be in the same network as the 1st NIC. The 2nd NIC should be cabled to a different physical switch than the 1st NIC, allowing for network redundancy without requiring confiuration on a different network.

    .First and foremost the goal of the HMC networking support is to provide the ability to achieve fully redundant network paths using the 2 customer network ports. Through the use of "current technologies" it would be possible to have these 2 customer network ports on the same logical network while still achieving physical redundancy. Using the same technologies It is also possible to easily achieve the same thing when these ports are not on the same logical network. By adding this capability, the 2 customer networks could be put on the same logical network even when there is not physical redundancy. Regardless of how much documentation is provided to warn that doing this would not provide complete physical redundancy, it would still be done. For this reason, adding this support is not something we intend to do.
