[PATCH 4.19 242/247] xfrm: interface: use icmp_ndo_send helper
From: Greg Kroah-Hartman
Date: Mon Mar 01 2021 - 16:43:59 EST
From: Jason A. Donenfeld <Jason@xxxxxxxxx>
commit 45942ba890e6f35232727a5fa33d732681f4eb9f upstream.
Because xfrmi is calling icmp from network device context, it should use
the ndo helper so that the rate limiting applies correctly.
