Bug 27722

Summary: 3C905TX / xl driver broken by mii bug
Product: Base System Reporter: wilko <wilko>

Description wilko freebsd_committer freebsd_triage 2001-05-28 22:50:01 UTC 
	Given mii/nsphy.c V1.8 in the kernel the 3COM cards do not
	autonegotiate anymore. Rather, they report 'no carrier'. 
	Manually forcing media to 10baseT/UTP does work. Manually forcing
	100baseTX does not work. In autonegotiate no link LEDs on the hub
	or the 3C905 are lit.

Fix: 

Revert to mii/nsphy.c V1.7 which does not 'enable some undocumented 
	bits' in the PHY chip. Apparantly this does work for fxp, but breaks
	xl on the 3C905-TX cards.

	Enable some undocumented bits in the DP83840 PHY, which is needed
	when using it with the Intel fxp driver.

Jonathan made the V1.7->V1.8 commit to nsphy.c and I assume/hope he can 
help fixing this one. I, for one, am not a network guy. Tnx.
Comment 2 Matthias Schuendehuette 2001-05-31 20:38:06 UTC 
For 4.3-STABLE:

nsphy.c Revision 1.2.2.3 (MFC on May 14th, 2001) is broken for 'xl'
nsphy.c Revision 1.2.2.2 works.
