Working on a PowerPC based custom board with linux3.10 gianfar ethernet driver, Come across a suitaion where the driver seems to be not going for an auto negotion when phy is up.
If the link is up when configuring the PHY, autoneg should always be re- negotiated, since uboot might have a different opinion about the link parameters. the commit bdb59f949d663b7e943fb5f40b2557af4314abf9 does seem to be stopping the driver to go for an auto negotiation.. Below the commits snipet + /* If the link is already up, we must already be ok, and don't need to + * configure and reset the TBI<->SerDes link. Maybe U-Boot configured + * everything for us? Resetting it takes the link down and requires + * several seconds for it to come back. + */ + if (gfar_local_mdio_read(regs, tbipa, MII_BMSR) & BMSR_LSTATUS) + goto done; + -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
