Hello!

I'm having very slow transfers (ftp) on my Linux box with the tulip driver. 
First some background -

Hardware - AlphaServer 300 4/266
Network Card - Integrated NIC  (10mbps)
OS - RedHat Linux 7.2 From HP/Compaq/RedHat

After the initial install, I could not get the machine to see the network 
at all.  No link light on my hub when the driuver loads.  If you issue a :

	/etc/rc.d/init.d/network stop

Then the link would come on.  This lead me to do some research and found 
variuous comments that the tulip driver included with RedHat had issues. 
So I downloaded the Net Drivers package :

	<http://www.scyld.com/network/tulip.html>

I compiled them and loaded them by hand :

	insmod pci-scan.o
	insmod tulip.o

And they loaded fine.  I then did a network start and the link went out. 
Forcing the options as such :

	insmod tulip.o options=4

Made the link light stay on and I had network connections. Whoo hoo!

Now however, when I try and FTP large files, they take forever ...

From my /var/log/messages file I see ...

I'm connected to a 10mbps switch port, that works fine with other machines. 
I've tried different ports etc, to no avail.


Any thoughts as to what I'm doing wrong ?

Thanks!


Michael
