My problem different, switch use one PHY address, but they (as I know) don`t provide identification. And I have to devices one on BCM5354 they have one bfe and one switch second on BCM5350 they have two bfe and one switch So I can`t only set hardcoded link bfe to bfeswitch. I need way for keeping auto probe and to know how fake switch id depend on outer info. >> >> ate0: <EMAC> mem 0xdffbc000-0xdffbffff irq 24 on atmelarm0 >> miibus0: <MII bus> on ate0 >> rlswitch0: <RTL8305SC 10/100 802.1q switch> PHY 0 on miibus0 >> rlswitch0: 100baseTX-FDX >> rlswitch1: <RTL8305SC 10/100 802.1q switch> PHY 1 on miibus0 >> rlswitch1: ignoring this PHY, non-zero instance >> device_attach: rlswitch1 attach returned 6 >> rlswitch2: <RTL8305SC 10/100 802.1q switch> PHY 2 on miibus0 >> rlswitch2: ignoring this PHY, non-zero instance >> device_attach: rlswitch2 attach returned 6 >> rlswitch3: <RTL8305SC 10/100 802.1q switch> PHY 3 on miibus0 >> rlswitch3: ignoring this PHY, non-zero instance >> device_attach: rlswitch3 attach returned 6 >> rlswitch4: <RTL8305SC 10/100 802.1q switch> PHY 4 on miibus0 >> rlswitch4: ignoring this PHY, non-zero instance >> device_attach: rlswitch4 attach returned 6 >> rlswitch5: <RTL8305SC 10/100 802.1q switch> PHY 5 on miibus0 >> rlswitch5: ignoring this PHY, non-zero instance >> device_attach: rlswitch5 attach returned 6 >> >> Beside from loocking strange it works fine this way. >> >> -- >> B.Walter <bernd@bwct.de> http://www.bwct.de >> Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm. -- Рыбалко Александр Консультант D-Link Украина
