From 552a515707a5caf9fa9f3620d68fc28146c6b1b9 Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Wed, 7 May 2014 09:28:31 +0200 Subject: [PATCH] ath9k: Allow platform override without EEPROM override Add a new platform data flag "use_eeprom" that indicates that the eeprom found on the card itself should be used instead of the one present in the platform data. This allows to override the MAC address of a PCI card while preserving the eeprom data from the card itself. The default behavior is preserved. Signed-off-by: Helmut Schaa Signed-off-by: John W.
