The via-rhine driver for the D-Link DFE-530TX NIC has problems with the newer cards. If the PCI IDs are 0x1106/0x3065 then this is a newer item. Under the RH7 2.2 kernel the module simply fails to load. Under the RH7 2.4 preview kernel the module loads, but the card lets out a stream of timouts and fails to actually emmit any traffic (viz tcpdump and activity lights). I have tested the platform under another OS and it works fine. The module code hasn't changed between the 2.4 preview kernel in rh7 and the 2.4.0-test11 kernel. This revised unit seems to be a shelf item in the stores over here in the UK. Andrew Meredith (RHCE RHCX)
Should be supported in latest errata.
