-Subject: [PATCH 2/6] bcm63xx_enet: do not write to random DMA channel on
- BCM6345
-
-The DMA controller regs actually point to DMA channel 0, so the write to
-ENETDMA_CFG_REG will actually modify a random DMA channel.
-
-Since DMA controller registers do not exist on BCM6345, guard the write
-with the usual check for dma_has_sram.
