Sabrina Dubroca a01cb66b26 xfrmi: drop ignore_df check before updating pmtu ... commit 45a36a18d0 upstream. xfrm interfaces currently test for !skb->ignore_df when deciding whether to update the pmtu on the skb's dst. Because of this, no pmtu exception is created when we do something like: ping -s 1438 <dest> By dropping this check, the pmtu exception will be created and the next ping attempt will work.
