Date: Fri, 14 Nov 2014 21:16:25 -0500 From: "Martin K. Petersen" <mkp@....net> To: netdev@...r.kernel.org Cc: linux.nics@...el.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [PATCH v3] ixgbe: Look up MAC address in Open Firmware or IDPROM Attempt to look up the MAC address in Open Firmware on systems that support it. On SPARC resort to using the IDPROM if no OF address is found. Signed-off-by: Martin K.
