From: Shahed Shaikh Date: Wed, 27 Aug 2014 16:43:20 +0000 (-0400) Subject: qlcnic: Add support to run firmware POST X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ced0a88cd4c86587cf9545f67a7b9ae63f78a4a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git qlcnic: Add support to run firmware POST This patch adds support to run Power On Self Test (POST) for 83xx adapters. POST can be run in 3 different speed modes : i) Fast mode (takes about 690 ms) ii) Medium mode (takes about 2930 ms) iii) Slow mode (takes about 7500 ms) To run POST, firmware file with name "83xx_post_fw.bin" should be present under /lib/firmware directory. load_fw_file module parameter is used to specify POST operation and its speed mode. load_fw_file = 2 : Fast mode load_fw_file = 3 : Medium mode load_fw_file = 4 : Slow mode Signed-off-by: Shahed Shaikh Signed-off-by: David S.
