-Subject: [PATCH] net: broadcom: bcm4908_enet: reset DMA rings sw indexes
- properly
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Resetting software indexes in bcm4908_dma_alloc_buf_descs() is not
-enough as it's called during device probe only. Driver resets DMA on
-every .ndo_open callback and it's required to reset indexes then.
-
-This fixes inconsistent rings state and stalled traffic after interface
-down & up sequence.
-
-Fixes: 4feffeadbcb2 ("net: broadcom: bcm4908enet: add BCM4908 controller driver")
