  • Thread-topic: (Summary) XenVif div by zero on Tx path after resume.

In summary:

- After reviewing the various suspend callbacks and the amount of rewrite that 
would be required to change the suspend / resume model, I think it's strongly 
preferable that we simply fix the case where xenvif gets a Tx packet request 
when frontend not initialized by just dropping the packet.
