I think it is most likely that you've missed something with regards to
making it thread safe. You could try something really simple that
should definitely work, such as having a single lock that controls
access to the stack, and anything calling any part of the stack must
first acquire this lock. I think things passing packets up from above
as well as calls from the application would need to be protected in
this way.
