From 76f43b4c0a9337af22827d78de4f2b8fd5328489 Mon Sep 17 00:00:00 2001 From: Masashi Honma Date: Thu, 8 Dec 2016 10:15:50 +0900 Subject: mac80211: Remove invalid flag operations in mesh TSF synchronization mesh_sync_offset_adjust_tbtt() implements Extensible synchronization framework ([1] 13.13.2 Extensible synchronization framework). It shall not operate the flag "TBTT Adjusting subfield" ([1] 8.4.2.100.8 Mesh Capability), since it is used only for MBCA ([1] 13.13.4 Mesh beacon collision avoidance, see 13.13.4.4.3 TBTT scanning and adjustment procedures for detail). So this patch remove the flag operations.
