The driver ethernet/tundra/tsi108_eth.c seems to be inconsistent about how
it shares buffers with the device. In the open function (tsi108_open), it
uses virt_to_phys. In the refill function (tsi108_refill_rx), it uses
dma_map_single. However, there doesn't seem to be any dma_unmap_single
anywhere.
I see that this is not a very actively maintained driver, but I am
interested in the general question of how this works.
thanks,
julia
