I have a working setup here with gigabit pause.  The pause bits come
from bits 11 and 10, just like for older copper PHYs.  Your link
parter is indicating that it has no pause capability.  That means
you can't use pause.
Interesting. I tried and it worked :-) Could be something funny in
the config of our switches.

Thanks for the explanation.

Cheers,
Ben.
