qlcnic: FW dump support
Added code to take FW dump. o Driver queries FW at the init time and gets the dump template o It takes FW dump as per the dump template o Level of FW dump (and its size) is configured via dump flag Signed-off-by: Sritej Velaga <sritej.velaga@qlogic.com> Signed-off-by: Anirban Chakraborty <anirban.chakraborty@qlogic.com> Signed-off-by: David S.
