Subject: [PATCH v4 net 2/5] gtp: use icmp_ndo_send helper
Date: Tue, 11 Feb 2020 20:47:06 +0100	[thread overview]
Message-ID: <20200211194709.723383-3-Jason@zx2c4.com> (raw)
In-Reply-To: <20200211194709.723383-1-Jason@zx2c4.com>

Because gtp is calling icmp from network device context, it should use
the ndo helper so that the rate limiting applies correctly.
