Subject: [PATCH V3 3/3] qca_spi: Fix reset behavior
Date: Wed, 6 Dec 2023 15:12:22 +0100 [thread overview]
Message-ID: <20231206141222.52029-4-wahrenst@gmx.net> (raw)
In-Reply-To: <20231206141222.52029-1-wahrenst@gmx.net>
In case of a reset triggered by the QCA7000 itself, the behavior of the
qca_spi driver was not quite correct:
- in case of a pending RX frame decoding the drop counter must be
incremented and decoding state machine reseted
- also the reset counter must always be incremented regardless of sync
state
Fixes: 291ab06ecf67 ("net: qualcomm: new Ethernet over SPI driver for QCA7000")
