Message-ID: <48CC259F.4000903@myri.com>
Date: Sat, 13 Sep 2008 22:42:07 +0200
From: Brice Goglin <brice@...i.com>
To: Jeff Garzik <jeff@...zik.org>, netdev@...r.kernel.org
Subject: [RESEND][PATCH 2.6.28] myri10ge: use DCA if DCA is compiled as a
module
Use DCA in myri10ge when CONFIG_DCA_MODULE is set as well.
And thus force INTEL_IOATDMA to =y so that DCA=y if we are =y.
