Subject: [PATCH RFC 1/5] net: add IFF_L2_ONLY flag
Date: Tue, 25 Aug 2015 15:50:11 -0700 [thread overview]
Message-ID: <1440543015-14693-2-git-send-email-f.fainelli@gmail.com> (raw)
In-Reply-To: <1440543015-14693-1-git-send-email-f.fainelli@gmail.com>
Allow network device drivers to flag specific network devices as being
L2 only, that is, no IPv4/v6 configuration will be allowed on these
interfaces, yet they are still usable as configuration endpoints for
ethtool interfaces.
