xfrm: iptfs: handle reordering of received packets

Browse source

Handle the receipt of the outer tunnel packets out-of-order. Pointers to
the out-of-order packets are saved in a window (array) awaiting needed
prior packets. When the required prior packets are received the now
in-order packets are then passed on to the regular packet receive code.
A timer is used to consider missing earlier packet as lost so the
algorithm will advance.
