Attached to this response was a beta-version of their (rl) driver. After a quick test it seemed to have fixed the problem. I have been trying to fix the issue in re(4) by looking at the changes in the beta-driver but have not had any success so far (due to lack of knowledge i guess). I put the beta driver up here: http://www.timkapel.nl/~laurens/rtl_bsd_drv_v174beta3.tgz > The other problem is that I have at least two applications misbehaving when > rxcsum/txcsum is enabled: > > - The Linux Second Life client (yes, yes, I know, but it is nice for showing > off GLX and it is really really good at generating network traffic) will > cease to receive data after about a minute or so - turning off rcxsum/txcsum > will mend it on the spot. > > - A Fedora Core 4 running in Qemu, networked with bridge(4) and tap(4), cannot > receive an ip address via DHCP.
