commit aa7d948369df87e0ba8767458959af84354d73ec Author: Sven Eckelmann sven@narfation.org Date: Mon Nov 5 10:15:24 2012 +0100

batctl: Fix alignment for payload after batadv_unicast_4addr_packet

batadv_unicast_4addr_packet created an odd aligned ethernet header and a not 4 bytes boundary aligned IP header. Adding an extra reserved bytes avoids this problem.

This problem was introduced in 78fc6bbe0aca868b65b92723b1e259e7ef7b35c0 ("batman-adv: add UNICAST_4ADDR packet type")
