From 75f25548bea11d35b7cb0879eea595d3f86a0cc4 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Fri, 13 Jan 2012 14:04:29 +0200 Subject: [PATCH] wl12xx: add testmode operation to read the BD_ADDR from Fuse ROM Add a testmode command to retrieve the BD_ADDR that is stored in the Fuse ROM in newer PGs. In old PGs this operation is not supported. The caller can then derive the MAC addresses from it.
