No need to stop ctlr if it was already stopped. It can cause timeout warns. Steps: - ifconfig eth0 down - ethtool -l eth0 rx 8 tx 8 - ethtool -l eth0 rx 1 tx 1 Signed-off-by: Ivan Khoronzhuk <redacted> --- Based on net-next/master drivers/net/ethernet/ti/davinci_cpdma.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
