Subject: [PATCH 154/170] Updated smsc95xx driver to check for a valid MAC
|
|
address in eeprom before using smsc95xx.macaddr parameter passed on command
|
|
line.
|
|
|
|
The built-in RPi adaptor will still get a MAC address based on the parameter passed on the command line as the RPi hardware does not have an eeprom,
|
|
however usb->ethernet adaptors using the same driver should have an eeprom with MAC address as part of their hardware and therefore will use this
|
|
meaning they don't end up with the same MAC address as the built-in RPi adaptor.
