From a83ce17cdd27c0978560ad54793ac7b7a3e27f54 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 19 Jun 2012 08:32:49 +0200 Subject: [PATCH] iwlwifi: fix 11n_disable EEPROM refactoring regression My commit 986fbacbc82 ("iwlwifi: refactor EEPROM reading/parsing") broke the 11n_disable module parameter's BIT(0) to disable all HT operation (using the other bits to disable aggregation only was unaffected). Restore this by overriding the SKU when parsing the EEPROM if the module parameter is set.
