The other half is PHY couldn't be detected. It seems that sis no longer implementes the enhanced phy control register, and phy has to be directly accessed via mdio. I have a patch (-stable only) for this problem, http://www.freebsd.org/~luoqi/sis.diff . I've also notice some other quirks of the chip our driver should be dealing with. Among them, the multicast address filter and DMA burst size. -lq To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
