Messages in this thread | | | Subject | [PATCH 4 0/4] Add ability to set defaultless network device MAC addresses to deterministic computed locally administered values | From | Andy Green <> | Date | Thu, 05 Jul 2012 10:44:33 +0800 |
| |
The following series adds some code to generate legal, locally administered MAC addresses from OMAP4 CPU Die ID fuse data, and then adds a helper at net/ethernet taking care of accepting device path / MAC mapping registrations and running a notifier to enforce the requested MAC when the matching network device turns up.
On PandaBoard / ES, two devices have no board-level MAC either assigned by the manufacturer or stored on the board, the last patch in the series adds these device paths and gets them set when the network device is registered.
Lastly for convenient testing, there's a little patch on omap2plus_defconfig that will get Ethernet and WLAN up on Pandaboard.
The patches are against today's linux-omap.
Thanks to Tony Lindgren and Arnd Bergmann for comments leading to the helper in net/ethernet.
