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

My dmesg contains:

and ifconfig -a gives:
