Any other ideas on this problem?  I am wondering if most people are
not complaining about it, because it is probably not noticeable for
web browsing (web browsing naturally has latencies involved).  It is a
killer for streaming stuff in "real time" between two machines,
though.

On my current machine with a 8111C NIC, I have disabled that NIC and
bought an Intel e1000 PCIe NIC.  That has solved the problem on that
computer, but I want to build another computer, and it seems like all
the new motherboards have the Realtek 8111C on them.

Should I try the "official" driver from Realtek?  How hard is it to integrate?

Thanks,

John
