| Subject: skge: Add DMA mask quirk for Marvell 88E8001 on ASUS P5NSLI motherboard |
| |
| |
| From: Graham Gower <graham.gower@gmail.com> |
| |
| [ 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. |

| |
| However, 18 months later a similar workaround was introduced for another |
| chipset exhibiting the same problem. |
