Disabling GRO on this device will likely work as temporary workaround.

What we can do is instead of dropping packets to correct their offset:

                case SKB_GSO_TCPV4:
                case SKB_GSO_TCPV6:
-                        if (skb->csum_offset != offsetof(struct tcphdr, check))
-                                return -EINVAL;
+                        if (skb->csum_offset != offsetof(struct tcphdr, check)) {
+                                DEBUG_NET_WARN_ON_ONCE(1);
+                                skb->csum_offset = offsetof(struct tcphdr, check);
+                        }

If the issue is in csum_offset. If the new csum_start check fails,
that won't help.

It would be helpful to see these values at this point, e.g., with
skb_dump(KERN_INFO, skb, false);
