From a2d79c5709659370cd2deeeeb8dc75bb0be5e318 Mon Sep 17 00:00:00 2001 From: Matti Gottlieb Date: Mon, 25 Aug 2014 14:41:23 +0300 Subject: iwlwifi: mvm: Add marker command 0xcb Add Marker command. The marker command send the ucode the time of sending the command in milliseconds since 1970-01-01 00:00:00 UTC, in addition to other metatdata. The ucode inserts this information into the usniffer logs, and returns the GP2 time stamp inside the command response.
