Subject: [PATCH] Handle upper case MAC addresses in ifname option
|
||
|
|
|
||
|
|
While the documentation states that ifname MAC addresses must be
|
||
|
|
lower case, we silently accept upper case ones and fail later on
|
||
|
|
when udev doesn't rename the device.
|
||
|
|
|
||
|
|
Instead of adding sanity checking on the MAC address just convert
|
||
|
|
it to lower case and remove the requirement completely.
