So I can now confirm that adding "phy_remove_link_mode(phy_dev, ETHTOOL_LINK_MODE_Asym_Pause_BIT);" fix the issue cause by 58056c1e1b0e.
The second problem (long time to got link) was due to my change of CONF_CARRIER_TIMEOUT.
I still dont understand why setting it to 3s (instead of 120) caused that.

I will send fixed patchs soon.
