The ones which weren't ported and applied to this branch are now part of this patch series. There are also following three patches included: * batman-adv: Consider fragmentation for needed_headroom * batman-adv: Reserve needed_*room for fragments * batman-adv: Don't always reallocate the fragmentation skb head which could in some circumstances cause packet loss but which were created to fix high CPU load/low throughput problems. But I've added them here anyway because the corresponding VXLAN patches were also added to stable. And some stable kernels also got these fixes a while back. Kind regards, Sven Linus Lüssing (1): batman-adv: mcast: fix duplicate mcast packets in BLA backbone from LAN Sven Eckelmann (3): batman-adv: Consider fragmentation for needed_headroom batman-adv: Reserve needed_*room for fragments batman-adv: Don't always reallocate the fragmentation skb head net/batman-adv/fragmentation.c | 26 ++++++++++++++++---------- net/batman-adv/hard-interface.c | 3 +++ net/batman-adv/multicast.c | 31 +++++++++++++++++++++++++++++++ net/batman-adv/multicast.h | 15 +++++++++++++++ net/batman-adv/soft-interface.c | 5 ++--- 5 files changed, 67 insertions(+), 13 deletions(-)
