Antonio Quartulli says:
====================
Included changes:
- avoid integer overflow in GW selection routine
- prevent race condition by making capability bit changes atomic (use
clear/set/test_bit)
- fix synchronization issue in mcast tvlv handler
- fix crash on double list removal of TT Request objects
- fix leak by puring packets enqueued for sending upon iface removal
- ensure network header pointer is set in skb
====================
