Comment:

 From reading the comments above, this bug is in dsaxena's lap at the
 moment, not cjb's.  (Although both will probably have to write a bit of
 code.)

 We could use a better testbed for exercising the "wake on network traffic"
 functionality, since we've got quite a bit of anecdotal evidence that it
 is at least slightly broken.  Once we fix this bug, it would be nice to be
 able to exercise the functionality more thoroughly to convince ourselves
 there aren't other lingering issues.  Perhaps a pair of simple scripts to
 exchange traffic between two XOs, forcing suspend at various times.  (What
 if, for example, the suspend decision happens after the kernel has sent an
 ACK for a packet but before the data is sent up to userland?  Probably
 better kernel integration is necessary to solve these problems
 completely.)
