From 487042af928c16d2a5b4dd52a9639a03b8b40761 Mon Sep 17 00:00:00 2001 From: Himanshu Madhani Date: Thu, 23 May 2013 21:04:33 +0000 Subject: [PATCH] qlcnic: Implement GET_LED_STATUS command for 82xx adapter. o GET_LED_STATUS command will be used by driver to get current beacon state from 82xx adapter. o Refactored qlcnic_store_beacon() to split 8200 and 8300 specific calls.
