Subject: [PATCH net 4/5] wireguard: use icmp_ndo_send helper
Date: Sun, 9 Feb 2020 15:31:42 +0100 [thread overview]
Message-ID: <20200209143143.151632-4-Jason@zx2c4.com> (raw)
In-Reply-To: <20200209143143.151632-1-Jason@zx2c4.com>
Because wireguard is calling icmp from network device context, it should use
the ndo helper so that the rate limiting applies correctly.
