NAPI is not enabled, it is the IRQ version. Hitting 

Added instrumentation:.

skb=0xd1e28380 len=8172 head=d1e32000 data=d1e32012 tail=d1e33ffe end=d1e32620

Looks like the board is running back-to-back packets together, MTU is 1500.
No Jumbo frames exist on my little network and the gigabit switch (Netgear) 
won't 
even take them.  Probably a chip bug.

Need to add a check for len > mtu before processing?
