This corrects an regression introduced by "net: Use 16bits for *_headers fields of struct skbuff" when NET_SKBUFF_DATA_USES_OFFSET is not set. In that case skb->tail will be a pointer however skb->network_header is now an offset. This patch corrects the problem by adding a wrapper to return skb tail as an offset regardless of the value of NET_SKBUFF_DATA_USES_OFFSET. It seems that skb->tail that this offset may be more than 64k and some care has been taken to treat such cases as an error. Signed-off-by:

The call to batadv_nc_skb_forward() fits better in batadv_send_skb_to_orig(), as this is where the actual next hop is looked up. To let the caller of batadv_send_skb_to_orig() know wether the skb is transmitted, buffered or failed, the return value is changed from boolean to int. Signed-off-by:

In order to make batman-adv fully vlan aware later, the semantic used for variables storing the VLAN ID values has to be changed in order to be adapted to the new one which will be used batman-adv wide. In particular, the VID has to be an "_unsigned_ short int" and its 4 MSB will be used as a flag bitfield, while the remaining 12 bits are used to store the real VID value Signed-off-by:

Instead of passing a generic combination of flags as argument, it is easier to pass the entire tt_common structure (containing the flags already set) plus a bitfield of event flags that will be unified with the already existing ones before inserting the client in the event queue. In this way invocations of the modified function can be simplified. Signed-off-by:

the sequence number is not stored in struct neigh_node, therefore there is no need to pass such value to the neigh_node creation procedure. At the moment the value is only used by a debug message, but given the fact that the seqno is not related to the neighbor object, it is better to print it elsewhere. Signed-off-by:

While it makes sense to send each broadcast thrice on 802.11 (WLAN) interfaces as broadcasts are often unreliable on these, there is no reason to do so on other interface types. The increased the overhead can be harmful on low-bandwidth links like VPN connections over slow internet lines, therefore it is better to reduce the number of broadcast packets sent on non-wireless links to one.

Previously batadv_is_wifi_iface() did two things at once: looking up a net_device from an interface index, and determining if it is a wifi device. The second part is useful itself when the caller already has a net_device reference. Signed-off-by:
