parentbatman-adv: make the AP isolation attribute VLAN specific (diff)
batman-adv: refine API calls for unicast transmissions of SKBs
With this patch the functions batadv_send_skb_unicast() and batadv_send_skb_unicast_4addr() are further refined into batadv_send_skb_via_tt(), batadv_send_skb_via_tt_4addr() and batadv_send_skb_via_gw(). This way we avoid any "guessing" about where to send a packet in the unicast forwarding methods and let the callers decide. This is going to be useful for the upcoming multicast related patches in particular. Further, the return values were polished a little to use the more appropriate NET_XMIT_* defines.
