BCM57416 - Mismatching link speed between ports on a 2 port device is not supported.

Latest firmware for the BCM57416 Dual port 10GBASE-T card states:

 

  - Mismatching link speed between ports on a 2 port device is not supported. (Eg: 10G on port 1 and 25G on port 2, is not a supported speed combination.)

 

 

Now, when we purchased these this was not a limitation issued.  I'm trying to get a clear reading on what this is saying.

 

Does it mean -

 

A) 1GB line on port (1) and a 10GB line on Port (2) OF THE SAME CARD is not supported 

 

or

 

B) 1 GB line on port (1) and a 10GB line on Port (2) OF THE SAME CARD and SAME PORT GROUP is not supported.


or

C)  none of the above and it's fine to run lines.

 

 

 

 

The reason I ask is we utilize these and they are working as card with PORT 1 at 1GB and PORT 2 at 10 GB. We are trying to chase down an unrelated issue on the system and want to clear the cards of possible blame.
