Yes, this is highly possible. My patch set which addressed all sorts of issues like this is now a year old, and I gave up with trying to get it merged - it became far too difficult to constantly update the patch set. I think Marek was going to look at taking over the patch set, but I've heard nothing from him. The patch set can be found at: git://ftp.arm.linux.org.uk/~rmk/linux-arm.git fec-testing but beware: not all of it is meant to be merged. That branch represents all patches I tried to solve various problems and improve performance and correctness (from the ARM architecture point of view). I did a lot of work to evaluate the effect of each individual patch, and tried to only include patches which did not cause a regression. From what I remember, every patch (apart from the branch head) from 7e291d514886 (net:fec: unsorted hacks) onwards was not well proven - but that was all done before the driver ended up with TSO support. Post TSO support, patches with "net: fec:" (note the space) /were/ good to go, but then the multiple-queue support got merged which completely screwed the patch set again. So, I just totally gave up.
