Subject: [PATCH RFC 4/5] net: dsa: Flag slave network devices with IFF_L2_ONLY
Date: Tue, 25 Aug 2015 15:50:14 -0700 [thread overview]
Message-ID: <1440543015-14693-5-git-send-email-f.fainelli@gmail.com> (raw)
In-Reply-To: <1440543015-14693-1-git-send-email-f.fainelli@gmail.com>
When tagging is not supported by the underlying switch driver,
ds->tag_protocol will be set to DSA_TAG_PROTO_NONE, and we should be
flagging the slave network devices with IFF_L2_ONLY such that IP
configuration is denied and they are just control end-points.
