Request #24323:

  submit:   home:geoffroy:MeeGo:1.2:IVI/kernel-adaptation-connext(r5) -> devel:kernel:1.2/kernel-adaptation-connext1


Message:
    * Tue Oct 18 2011 Geoffroy Van Cutsem <geoffroy.vancutsem at intel.com> - 2.6.37.6
- Backported 'mac_addr_str' parameter support
- This allows to set the MAC address when the driver is loaded instead
- of using a post-boot dirty hack. Good workaround for BMC #17418
