| Subject: asix: Check for supported Wake-on-LAN modes |
| |
| [ Upstream commit c4ce446e33d7a0e978256ac6fea4c80e59d9de5f ] |
| |
| The driver currently silently accepts unsupported Wake-on-LAN modes |
| (other than WAKE_PHY or WAKE_MAGIC) without reporting that to the user, |
| which is confusing. |
