Hi again.. Have tried 8139too drivers also and I had problem with that driver in 100 Mbit Duplex and Not duplex, but rtl8139.o goes faster when receiving data using FTP I'll get about 1.5MB/s UpStream and about 0.3MB/s downstream, when I use 10Mbit FullDuplex with 8139too driver I get about 0.8Mb/s upstream and about 0.9Mb/s downstream... By the way, Flowcontrol is not active, what good is it for and how do I active it if it exists? Below is some more info don't know where to get more info if there are any...
