FW will provide a TX rate per link for each FW status, and wlcore will be able to store the information for the use of the mesh hwmp module. This is used mainly in mesh. Rates are reported when a mesh interface is up. Signed-off-by: Maxim Altshul <maxim.altshul@ti.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
