From 63d76dc0b97230e012a128a898f56a55e763d91a 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 26a7ca9a71a ("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.
