Consider below mesh topology. MP1 / \ / \ MP2 --- MP3 Assume that even though MP1 & MP3 have direct mesh links, the path was established via MP2. (MP1 <-> MP2 <-> MP3). The 1-hop mesh link MP1 <-> MP3 never be excercised till the current path is terminated. As of now, there is no option to send data frame to pick other than primary path. So mesh link metric between MP1 & MP3 never be updated. This series allows user to send data to 1-hop mesh peers through unexercised mesh path. -Rajkumar Initial series: https://patchwork.kernel.org/project/linux-wireless/list/?series=80289&state=* Rajkumar Manoharan (3): cfg80211: add support to probe unexercised mesh link mac80211: add option for setting control flags mac80211: probe unexercised mesh links include/net/cfg80211.h | 6 +++++ include/net/mac80211.h | 2 ++ include/uapi/linux/nl80211.h | 16 +++++++++++++ net/mac80211/cfg.c | 1 + net/mac80211/ieee80211_i.h | 5 +++- net/mac80211/mesh_hwmp.c | 4 ++++ net/mac80211/tdls.c | 2 +- net/mac80211/tx.c | 47 ++++++++++++++++++++++++++++++++------ net/wireless/nl80211.c | 54 ++++++++++++++++++++++++++++++++++++++++++++ net/wireless/rdev-ops.h | 13 +++++++++++ net/wireless/trace.h | 19 ++++++++++++++++ 11 files changed, 160 insertions(+), 9 deletions(-) -- 1.9.1
