I wonder if anyone has the time to rewrite the realtek driver because
whenever anyone posts about rl0 the advice is always ditch the card, I agree
that realtek's are the reliant robin class of lan cards but the problems
people see do not happen on other operating systems with the same hardware,
eg. I have never seen that mtu problem on debian or windows but I have had
it myself on freebsd, I also get poor realtek performance but when I tried
linux with the same hardware it was normal.  Datacentre's far too often will
supply a realtek card with the machine so its not always possible or
affordable to simply ditch for a new brand.  If someone does have the time
to look at the driver it would be great and I would be available for testing
as I use realtek cards at home for my lan.
