I Finally ended up the big bisect operation. The commit responsible for
this issue is commit
b726e493e8dc13537d1d7f8cd66bcd28516606c3
labeled
'r8169: sync existing 8168 device hardware start sequences with vendor
driver'

With that patch removed, I  was able to get a sustained 40MB/s+ on a
20GB ftp transfer. I wasn't able to do it with the specified patch applied.
Just as a side note, I was never able to reproduce it on a 100MBit
connection, only on a full 1GBit one...

However this patch will not reverse on the current kernel.

What do you think the next step should be ?
As usual, if you need any testing, please do let me know.

Regards,
Rui Santos
