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 <shahed.shaikh@qlogic.com> Signed-off-by: David S.
