If anyone has any objections, please let me know. ------------------ From: Rengarajan S commit 799f532de13601f91ecb9cc6169d45d6e6933b0f upstream. Enabled ASD/ADD configuration for LAN7801 in the absence of EEPROM. After the lite reset these contents go back to defaults where ASD/ ADD is disabled. The check is already available for LAN7800.
