Subject: [PATCH 2/2] ipv4: flush ARP entries on device change
Date: Wed, 3 Mar 2010 16:01:14 +0200 [thread overview]
Message-ID: <1267624874-22326-2-git-send-email-timo.teras@iki.fi> (raw)
In-Reply-To: <1267624874-22326-1-git-send-email-timo.teras@iki.fi>
If device flag IFF_NOARP is changed, we should flush the ARP cache as all
entries need to get refreshed.
