Subject: [PATCH 2/6] rtw88: pci: reset dma when reset pci trx ring
Date: Thu, 28 Nov 2019 20:19:03 +0800 [thread overview]
Message-ID: <20191128121907.6178-3-yhchuang@realtek.com> (raw)
In-Reply-To: <20191128121907.6178-1-yhchuang@realtek.com>
From: Chin-Yen Lee <timlee@realtek.com>
When pci trx ring is reset, hw dma setting should be reset together.
Otherswise, the rx_tag of rx flow is not synchronous to hw.
