Subject: [PATCH AUTOSEL 4.14 002/105] ath10k: Do not send probe response template for mesh
Date: Mon, 15 Jul 2019 09:38:28 -0400	[thread overview]
Message-ID: <20190715134012.3226-2-sashal@kernel.org> (raw)
In-Reply-To: <20190715134012.3226-1-sashal@kernel.org>

From: Surabhi Vishnoi <svishnoi@codeaurora.org>

[ Upstream commit 97354f2c432788e3163134df6bb144f4b6289d87 ]

Currently mac80211 do not support probe response template for
mesh point. When WMI_SERVICE_BEACON_OFFLOAD is enabled, host
driver tries to configure probe response template for mesh, but
it fails because the interface type is not NL80211_IFTYPE_AP but
NL80211_IFTYPE_MESH_POINT.

To avoid this failure, skip sending probe response template to
firmware for mesh point.

Tested HW: WCN3990/QCA6174/QCA9984
