My answer isn't going to be very helpful to you, but there are likely a lot of changes in both the 3c905 driver and the TCP/IP stack in the kernel between RH 7.0 and RH 7.3. Your best bet may be just to stick with RH 6.0/7.0. You could always try taking the driver source from the RH 7.0 source tree, putting it into the 7.3/8.0 source tree and compiling it. That may or may not easily work. Even if it does, it may not solve your problem. -- David Hollister Furthurnet - Free, legal P2P - share the tunes: http://furthurnet.org -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
