SKYH4-2068 : Corrected Hub4 Operating Modes
SKYH4-2068 : Corrected Hub4 Operating Modes

Reason for change: The Hub4 does not allow the OperatingStandards to change and
only accepts the full set of standards and not a subset.

Test Procedure: 1. Verify that you can not set the 5GHz Operating standards to anything but
"a,n,ac"
2. Verify that you can not set the 2.4GHz Operating standards to anything but "b,g,n"

Risks: None
