From d25a8c1fa74f91c21a85b8379fbc8ba1a2ab322f Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Wed, 18 Jul 2018 08:31:43 +0200 Subject: [PATCH] net: qca_spi: Avoid packet drop during initial sync [ Upstream commit b2bab426dc715de147f8039a3fccff27d795f4eb ] As long as the synchronization with the QCA7000 isn't finished, we cannot accept packets from the upper layers. So let the SPI thread enable the TX queue after sync and avoid unwanted packet drop.
