Hi Max,
Le 28/01/2014 22:00, Max Filippov a écrit :
OpenCores 10/100 Mbps MAC does not support speeds above 100 Mbps, but does
not disable advertisement when PHY supports them. This results in
non-functioning network when the MAC is connected to a gigabit PHY connected
to a gigabit switch.
The fix is to disable gigabit speed advertisement on attached PHY
unconditionally.

Changes v1->v2:
- disable both gigabit advertisement and support.

This does not look necessary, you should not have to call
phy_start_aneg() because the PHY state machine is not yet started, at
best this calls does nothing.
