I tried specifying the media type manually, when I was trying to get nfe 
up and running earlier, I've reverted to auto now.

The box in question is currently running with your latest patch, I did 
manage to stress it (with a couple of concurrent ftp uploads+some web 
browing) into a state where it once again gave me a bunch of the following:

kernel: nfe0: discard frame w/o leading ethernet header (len 4 pkt len 4)
kernel: nfe0: discard frame w/o leading ethernet header (len 0 pkt len 0)
last message repeated 12 times
kernel: nfe0: discard frame w/o leading ethernet header (len 3 pkt len 3)
kernel: nfe0: discard frame w/o leading ethernet header (len 11 pkt len 11)
kernel: nfe0: discard frame w/o leading ethernet header (len 5 pkt len 5)
kernel: nfe0: discard frame w/o leading ethernet header (len 5 pkt len 5)
kernel: nfe0: link state changed to DOWN
kernel: nfe0: link state changed to UP

However bringing the interface down and up seemed to put it back into a 
normal state. (I just noticed that nfe0 went down/up again, without my 
interaction, if that matters).

ifconfig nfe0 yields:

nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=48<VLAN_MTU,POLLING>
        ether 00:1d:60:6d:73:ec
        inet 192.168.1.11 netmask 0xffffff00 broadcast 192.168.1.255
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
