Here is the summary with links:
  - [net-next,v8,1/6] can: use skb hash instead of private variable in headroom
    https://git.kernel.org/netdev/net-next/c/d4fb6514ff8e
  - [net-next,v8,2/6] can: add CAN skb extension infrastructure
    https://git.kernel.org/netdev/net-next/c/96ea3a1e2d31
  - [net-next,v8,3/6] can: move ifindex to CAN skb extensions
    (no matching commit)
  - [net-next,v8,4/6] can: move frame_len to CAN skb extensions
    https://git.kernel.org/netdev/net-next/c/d2d9179751e6
  - [net-next,v8,5/6] can: remove private CAN skb headroom infrastructure
    https://git.kernel.org/netdev/net-next/c/9f10374bb024
  - [net-next,v8,6/6] can: gw: use can_gw_hops instead of sk_buff::csum_start
