This is the twelfth revision of the basic multicast optimization patches.
Changes in v12 include (thanks for the feedback again, Marek and Simon):
* added three reserved bytes to the mcast TVLV container to have a four bytes alignment (thanks Simon) * Return value description in kernel docs for batadv_mcast_mla_tvlv_update added (thanks Marek) * Using eth_hdr() instead of skb->data in various places (thanks Marek) * Switched order of function parameters bat_priv and skb in various places for style consistency reasons (thanks Marek) * renamed one occurence of "BATMAN_IV" to "BATMAN" (thanks Marek) * kerneldoc for multicast_mode added (thanks Marek) * rebased on top of master * now that batadv_tt_local_add() has a potential failure case, a check for its return value was added
For Marek's question on gateway code interoperability, I reread that part and couldn't find any issues with it either. Moreover, any additional dhcp_rcp variable check seemed redundant to me, so I left that part as is.
Cheers, Linus
