[PATCH net V1 3/3] net: lan743x: Address problems with wake option flags configuration sequences

From: Raju Lakkaraju
Date: Tue Mar 19 2024 - 01:58:18 EST


WOL secure-on and magic packet configuration table:
--------------------------------------------------------------------------------
| Ethtool Ops | Send magic packet | Send magic packet | Send magic packet |
| | | with password | with wrong password|
--------------------------------------------------------------------------------
|WAKE_MAGIC (g) | wake | wake | wake |
--------------------------------------------------------------------------------
|WAKE_SECURE_MAGIC| no wake | wake | no wake |
| (s) | | | |
--------------------------------------------------------------------------------
| WAKE_MAGIC & | | | |
|WAKE_SECURE_MAGIC| wake | wake | wake |
| (gs) | | | |
--------------------------------------------------------------------------------
