While the AR9331 has a gigabit MAC towards the internal switch, the integrated PHYs however are only 100-base-tx capable. The existing code however advertieses gigabit capability in the link status word. If you attach such a PHY to a gigabit capable switch on the remote end, with some probability it attempts to negotiate gigabit and fails, falling baco to the AR9331 assuming a 10mbit half-duplex link. This has been observed quite frequently with the Carambola2 and gigabit capable switches. In ath79_register_eth(), "pdata->has_gbit = 1;" is set unconditionally for both AR9331 ethernet ports. This is most likely wrong. Despite the two MAC IP cores being gigabit MACs, the MAC for eth1 is connected to a 100base-T PHY via MII. The has_gbit attribute is used in the ethernet driver to determine the supported link modes. So either pdata->has_gbit is not set to 1 anymore, or the ethernet driver needs to be modified to determine the advertised link code word on another criteria than pdata->has_gbit. This patch implements the former solution. Signed-off-by: Harald Welte <laforge@gnumonks.org> SVN-Revision: 42432 |
