Public bug reported:
When running from a clean install with Hardy, All patches downloaded,
and a Realtek 8111C nic samab performance was about 2MB/sec. If you run
2 concurrent transfers this performance jumps to around 4.5MB/sec for
each transfer.
Using lshw -C network it showed that as default this using the R8169
driver.

Downloading the latest driver from realtek for the r8168 and compiling
it, I blacklisted the r8169 driver and insmod'ed the new driver. This
