-Subject: [PATCH] net: ethernet: mtk_eth_soc: handle dma buffer size soc
- specific
-
-The mainline MTK ethernet driver suffers long time from rarly but
-annoying tx queue timeouts. We think that this is caused by fixed
-dma sizes hardcoded for all SoCs.
-
-We suspect this problem arises from a low level of free TX DMADs,
-the TX Ring alomost full.
-
-The transmit timeout is caused by the Tx queue not waking up. The
-Tx queue stops when the free counter is less than ring->thres, and
-it will wake up once the free counter is greater than ring->thres.
-If the CPU is too late to wake up the Tx queues, it may cause a
-transmit timeout.
-Therefore, we increased the TX and RX DMADs to improve this error
-situation.
-
-Use the dma-size implementation from SDK in a per SoC manner. In
-difference to SDK we have no RSS feature yet, so all RX/TX sizes
-should be raised from 512 to 2048 byte except fqdma on mt7988 to
-avoid the tx timeout issue.
-
-Fixes: 656e705243fd ("net-next: mediatek: add support for MT7623 ethernet")

+Subject: [PATCH] net: ethernet: mtk_eth_soc: fix WED + wifi reset
+
+The WLAN + WED reset sequence relies on being able to receive interrupts from
+the card, in order to synchronize individual steps with the firmware.
+When WED is stopped, leave interrupts running and rely on the driver turning
+off unwanted ones.
+WED DMA also needs to be disabled before resetting.

+Subject: [PATCH] net: ethernet: mtk_eth_soc: handle dma buffer size soc
+ specific
+
+The mainline MTK ethernet driver suffers long time from rarly but
+annoying tx queue timeouts. We think that this is caused by fixed
+dma sizes hardcoded for all SoCs.
+
+We suspect this problem arises from a low level of free TX DMADs,
+the TX Ring alomost full.
+
+The transmit timeout is caused by the Tx queue not waking up. The
+Tx queue stops when the free counter is less than ring->thres, and
+it will wake up once the free counter is greater than ring->thres.
+If the CPU is too late to wake up the Tx queues, it may cause a
+transmit timeout.
+Therefore, we increased the TX and RX DMADs to improve this error
+situation.
+
+Use the dma-size implementation from SDK in a per SoC manner. In
+difference to SDK we have no RSS feature yet, so all RX/TX sizes
+should be raised from 512 to 2048 byte except fqdma on mt7988 to
+avoid the tx timeout issue.
+
+Fixes: 656e705243fd ("net-next: mediatek: add support for MT7623 ethernet")
