Here is the summary with links:
- [v3,net,1/3] flow_dissector: avoid u16 truncation of skb->len when computing thoff
https://git.kernel.org/netdev/net/c/99bda1ecbd56
- [v3,net,2/3] net: always dissect GSO packets in __virtio_net_hdr_to_skb()
https://git.kernel.org/netdev/net/c/44378d02c5aa
- [v3,net,3/3] selftests: net: tun: add test for VLAN-tagged GSO without NEEDS_CSUM

You are awesome, thank you!
