Description (partial)

When applying "hw-module breakout module 1 port 1 switch 1" config to switch, "show interface capability" will show rest of the 40G ports as 10G. Ports actual speed remains correct though.

On a 9500-12Q or 9500-24Q, the said problem will happen if the said breakout cmd is applied to the 1st port.
