Hello all,
I'm "playing with a Traverse Technologies Viking ADSL2+ card and here are my
experiences so far.
Firstly, although the 8139cp module is listed in rc.modules
astlinux # cat rc.modules
# These modules get modprobe'd when the system starts up.
#rtc
#Comment out the modules you don't need, and change the order to
#move eth0 to eth1, etc.

it doesn't exist on the system,
astlinux # modprobe 8139cp
FATAL: Module 8139cp not found.
astlinux # find / -name "8139*"
/sys/bus/pci/drivers/8139too

/lib/modules/2.6.27.49-astlinux/kernel/drivers/net/8139too.ko
The Ethernet controller on the Viking card is however being loaded with the
8139too driver.

but dmesg says "Use the "8139cp" driver for improved performance and stability."

So, 2 questions:
A) Where do I get a good 8139cp driver and will it be added to the next Astlinux
release?
B) How do I force the RTL8139cp to be eth0 and the "real" Ethernet card to be
eth1?
At the moment eth0 is the "real" Ethernet card (eepro100) but I don't understand
why it is loaded as eth0 when lspci puts it after the RTL8139cp (see lspci o/p
above).

If I change the network config in the GUI so that the external i/f is eth0 with
an address of 192.168.1.2 (the Vikings Ethernet i/f) and the internal network as
eth1 with the internal network address, when I reboot eth0 is _still_ the real
Ethernet card and I lock myself out because it now has the 192.168.1.2 address
instead of something in my network address range.
Sorry about the embedded "debug" output - I hope it doesn't make this mail too
difficult to read.
All the Best,
-Graham-
