Subject: [PATCH] omap2: set the ethaddr as well as the usbethaddr env var to
|
|
ensure static MAC
|
|
|
|
The kernel gets the ethernet MAC from the ethaddr variable, the omap boards for
|
|
devices with USB based eth adapters just set the usbethaddr which doesn't appear
|
|
to get passed to the kernel. The same Raspberry Pi code sets both ethaddr and
|
|
usbethaddr so lets do that so linux (tested 4.13 and 4.14) get a static rather
|
|
than a random MAC address, while not regressing users of usbethaddr.
