Slow Networking in 2.5/2.6

Slow Networking in 2.5/2.6

[Nico Schottelius]

[-- Attachment #1.1: Type: text/plain, Size: 711 bytes --]

Hello!

I am having problems with several cards in Linux 2.6:
   - 3com 3c905
   - rtl8139

The rates in a 100Mbit/s network I get are nearly exaclty
1MB/s.

Currently I am sitting on the notebook with the rtl8139 card,
so if someone has hints to debug this I can respond very fast.

Btw, yes, other hosts have better rates. Normally we have 8MB/s
when scp-ing:

Host me ---> fileserver: 1MB/s
Host me ---> host test: 1MB/s
Host other ---> fileserver: 8MB/s
Host test ---> fileserver: 5-7MB/s

Greetings,

Nico

ps: dmesg attached

Well, now I have some more information, which make me wonder:

I am currently trying to debug the rtl8139 card:

00:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8139/8139C/8139C+ (rev 10)

00:05.0 Class 0200: 10ec:8139 (rev 10)

        Interrupt: pin A routed to IRQ 5
        Region 0: I/O ports at d600 [size=256]
        Region 1: Memory at effaee00 (32-bit, non-prefetchable) [size=256]

ot+,D3cold+)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-

What makes me wondering is the attached output of mii-diag and
8139-diag, can somebody tell me why the values are non standard and
why the flow control is disabled?

Greetings,

Nico
