OK... So I tried to disable offloading on the WAN interface (eth0.2 for 
the DIR-860L), but that throws the following error:

# ethtool -K tso off gso off gro off eth0
Cannot get device feature names: No such device

Same for any other devices I try... Is there a way to disable 
offloading without ethtool?
