Thanks. It seems that the PHY is reporting that everything is fine,
all the various blocks associated with the SFP+ cage are reporting
that link is established, and link is established with the host.
I wonder - can you tcpdump to see whether any traffic is being
received at either end of the link, in case it's only one direction
that is a problem?
