+The values were obtained from vendor bios at runtime.
+I am not 100% sure of the sequence required to initiate them,
+but guessed from the gm45 code. There may be some status bytes
+needed to be polled during the sequence that is missing,
+but as I don't have bios writer's datasheet it's very hard
+for me to know.

+
+One thing that is vital to this patch is the MAC address setting
+in case the EEPROM/efuse is unconfigured.
+Linux now recognises the default MAC address on GA-G41M-ES2L which
+does rely on the default bios settings for the MAC address.
