I finally had some time to run some quick tests on my laptop which is
using the r8169 driver.
As a general comment, everything seems to be working OK, and I saw no
errors.
Here's the device I'm using:

Unfortunately, I haven't executed all the tests you have suggested.
Basically, I have executed the netperf tests but I couldn't see any
relevant throught modifications. I recorded the netperf test logs here:
http://henrix.tuxfamily.org/netdev/
You'll find 2 directories: one with the tests results for the kernel
packaged I downloaded from people.debian.org and another using my own
custom 2.6.39 kernel.
I have also executed the suspend to memory/disk tests. Everything seems
to work as expected.
Although I was not able to run all the tests you are asking (both for the
lack of free time and for lack of knowledge -- No idea how to test the VLAN
stuff, for example) I hope these test report can help. Any comments are
appreciated about anything wrong I might have done.
