Thanks for reviewing!

Sorry, it seems to break the zerocopy send flow, and I've tested only 
with the receive flow offload disabled.

I'll fix it in v4. I think that adding a flag to indicate whether a 
revert is needed should do the trick. In the receive flow the revert is 
needed to handle potential errors, while in the transmit flow it needs 
to be removed.
