Linux kernel source tree

When batadv_tp_handle_out_of_order inserts a new entry in the list of
unacked (out of order) packets, it searches from the entry with the newest
sequence number towards oldest sequence number. If an entry is found which
is older than the newly entry, the new entry has to be added after the
found one to keep the ascending order.
But for this operation list_add_tail() was used. But this function adds an
entry _before_ another one. As result, the list would contain a lot of
swapped sequence numbers. The consumer of this list
(batadv_tp_ack_unordered()) would then fail to correctly ack packets.
