Mika Westerberg 540c11159d net: thunderbolt: Stop using zero to mean no valid DMA mapping ... Commit 86dabda426 ("net: thunderbolt: Clear finished Tx frame bus address in tbnet_tx_callback()") fixed a DMA-API violation where the driver called dma_unmap_page() in tbnet_free_buffers() for a bus address that might already be unmapped. The fix was to zero out the bus address of a frame in tbnet_tx_callback(). However, as pointed out by David Miller, zero might well be valid mapping (at least in theory) so it is not good idea to use it here. It turns out that we don't need the whole map/unmap dance for Tx buffers at all. Instead we can map the buffers when they are initially allocated and unmap them when the interface is brought down. In between we just DMA sync the buffers for the CPU or device as needed. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: David S.
