Description (partial)

On AnyConnect NAM 3.1 versions, when a continuous ping is running, one can observe occasional high RTT latency and ping timeouts.

To reproduce this issue, load anyconnect 3.1 NAM on any device using wireless networking. Use any authentication. Set up a continuous ping, and notice the RTT and ping timeouts. This may take several minutes. Next, install any 3.0 version (we used MR8 and MR11) and run the same continuous ping and notice the even RTT and lack of ping timeouts.
