Subject: [PATCH AUTOSEL 5.4 248/350] ath10k: fix get invalid tx rate for Mesh metric

From: Miaoqing Pan <miaoqing@...eaurora.org>

[ Upstream commit 05a11003a56507023f18d3249a4d4d119c0a3e9c ]

ath10k does not provide transmit rate info per MSDU
in tx completion, mark that as -1 so mac80211
will ignore the rates. This fixes mac80211 update Mesh
link metric with invalid transmit rate info.

Tested HW: QCA9984
Tested FW: 10.4-3.9.0.2-00035
