I've been fighting with a 3com 3c905 10/100 card for the last month or so, a
friend helped me narrow down the problem, but it's still not working even
remotely as well as it should be.
Hardware:
From dmesg:
xl0: <3Com 3c905-TX Fast Etherlink XL> port 0xd400-0xd43f irq 10 at device
12.0 on pci0
xl0: Ethernet address: 00:60:08:a5:99:b2
miibus0: <MII bus> on xl0
nsphy0: <DP83840 10/100 media interface> on miibus0
nsphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
The Switch:
NetGear FS105 10/100.
The problem:
when the card and switch autonegotiate a link, they agree on 100Mb Full
Duplex. This works fine copying files _to_ the FreeBSD box. They come down
at 3MB/s from my linux box. Copying the same file from the FreeBSD box _to_
the linux box happens at 20-30KB/s
So copying the 15 MB test file I was using one way took 5 seconds, the other
way took 9 minutes.
Things I've done:
Switched ports on the hub: no effect.
Switched cables: no effect.
upgraded the the latest STABLE: increased upload speed to 30-40KB/s
switched off newreno and delayed ack: no effect.
forced the card into 10baseT/UTP: both upload and download speeds became
900KB/s (Which is about right for 10baseT)
Any help? Suggestions?
Thanks
Bryan Kilian
