Hi David
I'm pretty sure mlxbf_gige_get_pauseparam() is broken.
This is the only code which sets priv->rx_pause, etc. And this is
before the PHY has had time to do anything. auto-neg has not completed
so you have no idea what has been negotiated for pause.
mlxbf_gige_adjust_link() should be adjusting priv->??_pause once the
link has been established.
