Subject: [PATCH net-next 2/3] net: packet: use reciprocal_divide in fanout_demux_hash
Date: Wed, 28 Aug 2013 22:13:10 +0200 [thread overview]
Message-ID: <1377720791-15844-3-git-send-email-dborkman@redhat.com> (raw)
In-Reply-To: <1377720791-15844-1-git-send-email-dborkman@redhat.com>
Instead of hard-coding reciprocal_divide function, use the inline
function from reciprocal_div.h.
