It seems that mii_ticks is not kicked at all in auto-negotiation phase. From the output of forced 1000baseSX media configuration I guess BRGPHY_BMSR_ACOMP bit in BRGPHY_MII_BMSR is not updated on 5708S. Mabe davidch know better what's going on 5708S. (CCed) How about attached patch? I don't have the hardware so it's just a guess work. -- Regards, Pyun YongHyeon --xgyAXRrhYN0wYx8y Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="brgphy.patch" Index: brgphy.c =================================================================== RCS file: /home/ncvs/src/sys/dev/mii/brgphy.c,v retrieving revision 1.70 diff -u -r1.70 brgphy.c --- brgphy.c 8 Jun 2007 02:34:44 -0000 1.70 +++ brgphy.c 26 Nov 2007 05:03:55 -0000 @@ -364,12 +364,10 @@ break; } -#if 0 /* Todo: Is this correct? */ /* Announce link loss right after it happens. */ if (sc->mii_ticks++ == 0) break; -#endif /* Only retry autonegotiation every mii_anegticks seconds. */ if (sc->mii_ticks <= sc->mii_anegticks) @@ -507,9 +505,12 @@ /* Autoneg is still in progress. */ if ((bmcr & BRGPHY_BMCR_AUTOEN) && (bmsr & BRGPHY_BMSR_ACOMP) == 0) { - /* Erg, still trying, I guess... */ - mii->mii_media_active |= IFM_NONE; - goto brgphy_status_exit; + /* XXX 5708S doesn't update BRGPHY_BMSR_ACOMP? */ + if ((bsc->serdes_flags & BRGPHY_5708S) == 0) { + /* Erg, still trying, I guess... */ + mii->mii_media_active |= IFM_NONE; + goto brgphy_status_exit; + } } /* Autoneg is enabled and complete, link should be up. */ --xgyAXRrhYN0wYx8y--
