[realtek] Linux Driver for DLink DFE-530TX+

[Joe Fago]

Hi,

I got this driver working, but the 2.2.18 stock rtl8139.o and 8139too.o modules
do not detect the card. I tried 2.4.1, and its 8139too.o module did not detect
it either. I had to use the pci-scan.o and rtl8139.o v1.13 combo from

`working' is really an overstatement...

On large sustained ftps my transfer rate is only about 10-16 MBits/S.
I usually see several of these:

exiting interrupt, intr_status=00000011

[Rx Buffer overflow, set when the Rx ring overflows due to high interrupt latency]

then some 00000030s
-- which I have no clue what those could be.


Eventually, I get: Oversized Ethernet frame, status 84f2c759!
                       or:  Oversized Ethernet frame, status d00c1e7a!

it changes each time.

Good news (sort of) is that:

$ ifconfig eth1 down
$ ifconfig eth1 192.168.1.1

gets communications going again. until another large transfer.


This is my gateway, its a pentium(cyrix PR) 166MHz, 32M.
PCI config:
Burst mode enabled.
CPU to PCI Write buffer enabled.
PCI activated by level (seemed to work better than edge).


Another point is that the card is a DFE-530TX+, but the driver detects a
DFE-538TX...
