Subject: [PATCH 12/14] pktgen: use common idle routine
Date: Thu, 27 Aug 2009 16:55:18 -0700 [thread overview]
Message-ID: <20090827235706.063577285@vyatta.com> (raw)
In-Reply-To: 20090827235506.624381734@vyatta.com
[-- Attachment #1: pktgen-idle-common.patch --]
[-- Type: text/plain, Size: 976 bytes --]
Simpler to have one place that spins and accounts for delays,
this will also make the last packet be detected faster for more
repeatable timing.
