From 380fd8550acc9c04fb2b7835a9663b5a0e53b840 Mon Sep 17 00:00:00 2001 From: Graham Gower Date: Mon, 8 Oct 2012 08:34:50 +0000 Subject: [PATCH] skge: Add DMA mask quirk for Marvell 88E8001 on ASUS P5NSLI motherboard [ Upstream commit a2af139ff1cd85df586690ff626619ab1ee88b0a ] Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive packets on a system with >4gb ram unless a 32bit DMA mask is used. This issue has been around for years and a fix was sent 3.5 years ago, but there was some debate as to whether it should instead be fixed as a PCI quirk. http://www.spinics.net/lists/netdev/msg88670.html However, 18 months later a similar workaround was introduced for another chipset exhibiting the same problem. http://www.spinics.net/lists/netdev/msg142287.html Signed-off-by: Graham Gower Signed-off-by: Jan Ceuleers Acked-by: Stephen Hemminger Signed-off-by: David S.
