| Subject: igb: Exclude device from suspend direct complete optimization |
| |
| [ Upstream commit 5b6e13216be29ced7350d9c354a1af8fe0ad9a3e ] |
| |
| igb sets different WoL settings in system suspend callback and runtime |
| suspend callback. |
| |
| The suspend direct complete optimization leaves igb in runtime suspended |
| state with wrong WoL setting during system suspend. |
| |
| To fix this, we need to disable suspend direct complete optimization to |
| let igb always use suspend callback to set correct WoL during system |
| suspend. |
