Subject: [PATCH RFC 2/5] net: ipv4: Skip in_dev initialization for IFF_L2_ONLY interfaces
Date: Tue, 25 Aug 2015 15:50:12 -0700 [thread overview]
Message-ID: <1440543015-14693-3-git-send-email-f.fainelli@gmail.com> (raw)
In-Reply-To: <1440543015-14693-1-git-send-email-f.fainelli@gmail.com>
IFF_L2_ONLY interfaces are Layer-2 only and do not support configuration
of IPv4 addresses, nor the full IPv4 protocol stack. Do nothing for
these interfaces.
