mainline inclusion from mainline-v5.17-rc1 commit 429e3d123d9a50cc9882402e40e0ac912d88cfcf category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7NDRB CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------
Wrong hash sends single stream to multiple output interfaces.
The offset calculation was relative to skb->head, fix it to be relative to skb->data.
