um... where would it be dropping that we wouldn't have a bug? I mean
sure faster is great... but if it makes my network not work right...

I've added all (I think) information you've asked for to the bug except for ethtool
and netstat on the router side. ethtool complains about not having
driver or capability (maybe because it's a 2.4 kernel?) and the
version of netstat doesn't support -s. I disabled everything that I
can think of that would send/receive packets before doing the test
client side, except dhcp/dns windows box's were probably sending some
broadcasts too. but the traffic should be pretty low. I did remember
to set the txqueuelen didn't seem to make a difference

only error in dmesg I see is

e1000e 0000:00:19.0: pci_enable_pcie_error_reporting failed 0xfffffffb

but it's in working versions too.
