Problem with nfe stability and throughput

Hi,
I've installed CURRENT on an asus m2n-vm. My network config is giving me
problems.
Throughput seems low. I'm seeing up/download rates less than 1 Mbyte/sec
on my local lan (100Mb). I've tried switching cables/ports in my switch etc.
I've enabled device polling (hz=1000)
Uploads from the box are slow but "stable". Downloads to the box are
both slow and unstable. After a few seconds i see the following lines in
my log and all transfers freeze. Doing ifconfig nfe0 down/up brings the
interface back to life.
nfe0: discard frame w/o leading ethernet header (len 3 pkt len 3)
nfe0: discard frame w/o leading ethernet header (len 0 pkt len 0)
nfe0: discard frame w/o leading ethernet header (len 8 pkt len 8)
nfe0: discard frame w/o leading ethernet header (len 0 pkt len 0)
I've tried applying the patch from this conversation:
http://www.nabble.com/nfe-busted-on-7.0-BETA4-to14143721.html#a14143721
but i still see the same error. (My dmesg/ifconfig output in the bottom
of this mail)
Could someone please give me some pointers on how to fix these things?
TIA
