Um, you simply increase the size of the elp_packet? Isn't this potentially 
breaking compat with older versions? batadv_v_elp_packet_recv is using 
BATADV_ELP_HLEN (sizeof(struct batadv_elp_packet)) as minimal size/header_len 
in batadv_check_management_packet.

Only thing saving you here is the padding on some links. But this padding 
could cause some odd behaviour in batadv_tvlv_containers_process2 when 
tvlv_len is bogus/padding.

Kind regards,
