Subject: [PATCHv2 ipsec-next 09/10] xfrm: interface: support IP6IP6 and IP6IP tunnels processing with .cb_handler
Date: Tue, 30 Jun 2020 15:36:34 +0800 [thread overview]
Message-ID: <c13ffdfb739d487a415897b72bf8eee6981830c6.1593502515.git.lucien.xin@gmail.com> (raw)
In-Reply-To: <088d28eeaf2ba1d7d24cd112a813c57583c5547b.1593502515.git.lucien.xin@gmail.com>
In-Reply-To: <cover.1593502515.git.lucien.xin@gmail.com>
Similar to ip6_vti, IP6IP6 and IP6IP tunnels processing can easily
be done with .cb_handler for xfrm interface.
