It does 10 and 1000 just fine. My Zedboard does not have this problem. The boards have different phys: The Zedboard uses the ukphy driver and the Zybo uses the rgephy driver. I just suspected the rgephy driver needed a tweak to work with my specific phy but I never got around to investigating it. And it looks like the Rockchip also uses the rgephy driver. On my Zybo, sysctl dev.rgephy returns this... dev.rgephy.1.%parent: miibus0 dev.rgephy.1.%pnpinfo: oui=0xe04c model=0x11 rev=0x5 dev.rgephy.1.%location: phyno=1 dev.rgephy.1.%driver: rgephy dev.rgephy.1.%desc: RTL8169S/8110S/8211 1000BASE-T media interface dev.rgephy.0.%parent: miibus0 dev.rgephy.0.%pnpinfo: oui=0xe04c model=0x11 rev=0x5 dev.rgephy.0.%location: phyno=0 dev.rgephy.0.%driver: rgephy dev.rgephy.0.%desc: RTL8169S/8110S/8211 1000BASE-T media interface dev.rgephy.%parent: --Thomas -- ===== Thomas Skibo thomas-bsd@skibo.net
