Subject: [net-next 1/2] ip6_tunnel: put ip6tnl0 FB device into 'any' mode
Date: Tue, 21 Oct 2014 12:11:27 +0400 [thread overview]
Message-ID: <1413879088-13513-1-git-send-email-alan@al-an.info> (raw)
The fallback device is in ipv6 mode by default.
The mode can not be changed in runtime, so there
is no way to decapsulate ip4in6 packets coming from
various sources without creating the specific tunnel
ifaces for each peer.
