Subject: [PATCH net-next v2 2/5] net: l2tp: only set L2TP_ATTR_UDP_CSUM if AF_INET
Date: Mon, 7 Nov 2016 20:39:25 +0000 [thread overview]
Message-ID: <20161107203928.30111-2-asbjorn@asbjorn.st> (raw)
In-Reply-To: <20161107203928.30111-1-asbjorn@asbjorn.st>
Only set L2TP_ATTR_UDP_CSUM in l2tp_nl_tunnel_send()
when it's running over IPv4.
This prepares the code to also have IPv6 specific attributes.
