Subject: [PATCH v5 net 3/3] lan78xx: Use default values loaded from EEPROM/OTP after reset
Date: Thu, 21 Sep 2017 02:36:38 +0530 [thread overview]
Message-ID: <20170920210638.11150-4-Nisar.Sayed@microchip.com> (raw)
In-Reply-To: <20170920210638.11150-1-Nisar.Sayed@microchip.com>
Use default value of auto duplex and auto speed values loaded
from EEPROM/OTP after reset. The LAN78xx allows platform
configurations to be loaded from EEPROM/OTP.
Ex: When external phy is connected, the MAC can be configured to
have correct auto speed, auto duplex, auto polarity configured
from the EEPROM/OTP.
Fixes: 55d7de9de6c3 ("Microchip's LAN7800 family USB 2/3 to 10/100/1000 Ethernet device driver")
