net: ethernet: ti: davinci_cpdma: allow desc split while down
That's possible to set ring params while interfaces are down. When interface gets up it uses number of descs to fill rx queue and on later on changes to create rx pools. Usually, this resplit can happen after phy is up, but it can be needed before this, so allow it to happen while setting number of rx descs, when interfaces are down. Also, if no dependency on intf state, move it to cpdma layer, where it should be. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
