On some dual-port cards, 10G and 25G are not compatible.  If one port
links up at 25G, for example, the other port will never link up if it
is set to 10G.  In this case the 10G port gets a message from the
firmware and the driver will print the "10G no longer supported"
message.  It's supposed to be a one time message.
