| Subject: net: qca_spi: Avoid packet drop during initial sync |
| |
| From: Stefan Wahren <stefan.wahren@i2se.com> |
| |
| [ 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. |
