Auto-negotiation has been broken for me since the following commit:
jlemon 2001/03/14 11:50:37 PST
Modified files:
sys/dev/fxp if_fxp.c if_fxpreg.h if_fxpvar.h
Log:
Add some performance features to the fxp driver. If the chip is not
a 82557 (e.g.: a newer chip) then:
+ enable MWI, if the PCI configuration indicates the system supports
it
+ enable usage of extended TxCB, for better performance
+ enable hardware flow control. FC frames will be passed up to the
host only if promiscuous mode is enabled.
Revision Changes Path
1.109 +67 -27 src/sys/dev/fxp/if_fxp.c
1.22 +6 -3 src/sys/dev/fxp/if_fxpreg.h
1.17 +4 -1 src/sys/dev/fxp/if_fxpvar.h
I have a releng_3 machine with multiple fxp cards acting as a sort of
gateway/router, and my workstation running -current (and dual-booting
windows) with an fxp card connected to it by a crossover cable. For various
reasons (mostly windows brokeness) I force "netmask 255.255.255.0 media
100baseTX mediaopt full-duplex" on both ends. The first commit of the
miibus'ified driver worked with this configuration, but since 3/14 it
hasn't. Sorry for the delay in reporting, but I haven't had time to confirm
till tonight. A kernel built before 3/14 works, everything after is broken.
If I leave out the media and mediaopt options It'll autonegotiate media:
autoselect (100baseTX) status: active, but I can't get full-duplex at all.
Let me know if there's anything I can test, more details needed, etc.
