net: orphan frags on stand-alone ptype in dev_queue_xmit_nit
Zerocopy skbs frags are copied when the skb is looped to a local sock.
Commit 1080e512d44d ("net: orphan frags on receive") introduced calls
to skb_orphan_frags to deliver_skb and __netif_receive_skb for this.
With msg_zerocopy, these skbs can also exist in the tx path and thus
loop from dev_queue_xmit_nit. This already calls deliver_skb in its
loop. But it does not orphan before a separate pt_prev->func().
Add the missing skb_orphan_frags_rx.
Changes
v1->v2: handle skb_orphan_frags_rx failure
Fixes: 1f8b977ab32d ("sock: enable MSG_ZEROCOPY")
