Subject: [PATCH 09/12] net: qca_spi: Avoid packet drop during initial sync
Git-commit: b2bab426dc715de147f8039a3fccff27d795f4eb
Patch-mainline: v4.18-rc6
References: git-fixes
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.
