Subject: [PATCH] cangen: allow double value for gap
Date: Wed, 11 Jul 2012 16:23:12 +0200	[thread overview]
Message-ID: <1342016592-1401-1-git-send-email-alexander.stein@systec-electronic.com> (raw)

This way a user can specify a gap below 1ms. This is somehwat similar
to setting the gap to 0, but the ENOBUFS are greatly reduced, so a given
amount of CAN messages by -n is still usefull and useable.
