batman-adv: restructure rebroadcast counter into forw_packet API
This patch refactors the num_packets counter of a forw_packet in the following three ways: 1) Removed dual-use of forw_packet::num_packets: -> now for aggregation purposes only 2) Using forw_packet::skb::cb::num_bcasts instead: -> for easier access in aggregation code later 3) make access to num_bcasts private to batadv_forw_packet_*() Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue> [sven@narfation.org: Change num_bcasts to unsigned] Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Simon Wunderlich <sw@simonwunderlich.de>
