Re: [B.A.T.M.A.N.] [PATCHv4 1/7] batman-adv: implement an helper function to forge unicast packets

A new function named prepare_unicast_packet() has been implemented so that it can do all the needed operations to set up a skb for unicast sending. It is general enough to be used in every context. Helpful for later developments

When Sven added this header structure, did he also add a function to fill it in?
