Subject: [PATCH] net: arp: use assignment
Date: Thu,  2 Dec 2010 14:07:31 +0800	[thread overview]
Message-ID: <1291270051-27109-1-git-send-email-xiaosuo@gmail.com> (raw)

Only when dont_send is 0, arp_filter() is consulted, so we can simply
assign the return value of arp_filter() to dont_send instead.
