[realtek] timeout problem with 8139too.c

[xin chen]

Hi,
I'm using a rtl8139c ethernet card in an embedded
system. Linux 2.4.3 runs on a MIPS CPU (does it
matter?) and controls the ethernet card through a
backplane of PCI bus. The card is test within a PC, it
can run smoothly. But on the embedded system, it can
be detected and initialized, the 8139too.c version
0.9.15c is loaded, but it will have errors of
transimit timeout. Following is debug messages when I
set the "RTL8139_DEBUG" in  8139too.c.

I know following messages looks terrible...But in
order to give enough information for you to give any
hints...Thanks in advance.


if ifconfig eth0....
...
