From aaba215ca0b4232824c92b830853f465f16a6672 Mon Sep 17 00:00:00 2001 From: Jeff Kirsher Date: Wed, 14 Sep 2011 21:23:14 +0000 Subject: [PATCH] MII: fix Kconfig dependencies for MII MII Kconfig option is apart of the core networking drivers and by default NET_CORE is enabled so drivers selecting MII will have MII enabled as well. It was found using the randconfig option during testing, MII would be selected but NET_CORE could be disabled. This caused a dependency error. Resolved the dependency by selecting NET_CORE when MII is selected. Reported-by: Emil Tantilov Signed-off-by: Jeff Kirsher Tested-by: Aaron Brown Signed-off-by: David S.
