[PATCH net] ipv6: Paritially checksum full MTU frames

[RFC PATCH net-next 3/3] macvtap: Record the rx queue based on the user tap queue

Now that macvlan has a basic queue selection and macvtap has multiple qdiscs, we can record the the queue index into the skb based on the index of the macvtap user queue. This index will then be used to select the right qdisc. Signed-off-by: Vlad Yasevich --- drivers/net/macvtap.c | 1 + 1 file
