-We need to update the skb->csum after pulling the skb, otherwise
-an unnecessary checksum (re)computation can ocure for IGMP/MLD packets
-in the bridge code. Additionally this fixes the following splats for
-network devices / bridge ports with support for and enabled RX checksum

-Subject: [PATCH 223/232] bpf: add skb_postpush_rcsum and fix dev_forward_skb
- occasions
-
-Add a small helper skb_postpush_rcsum() and fix up redirect locations
-that need CHECKSUM_COMPLETE fixups on ingress. dev_forward_skb() expects
-a proper csum that covers also Ethernet header, f.e. since 2c26d34bbcc0
-("net/core: Handle csum for CHECKSUM_COMPLETE VXLAN forwarding"), we
-also do skb_postpull_rcsum() after pulling Ethernet header off via
-eth_type_trans().
-
-When using eBPF in a netns setup f.e. with vxlan in collect metadata mode,
-I can trigger the following csum issue with an IPv6 setup:
-

-  [...]
-
-What happens is that on ingress, we push Ethernet header back in, either
-from cls_bpf or right before skb_do_redirect(), but without updating csum.
-The "hw csum failure" can be fixed by using the new skb_postpush_rcsum()
-helper for the dev_forward_skb() case to correct the csum diff again.
-
-Thanks to Hannes Frederic Sowa for the csum_partial() idea!
