veth: always report zero combined channels
veth get_channel currently reports for channels being both RX/TX and combined. As Jakub noted: """ ethtool man page is relatively clear, unfortunately the kernel code is not and few read the man page. A channel is approximately an IRQ, not a queue, and IRQ can't be dedicated and combined simultaneously """ This patch changes the information exposed by veth_get_channels, setting max_combined to zero, being more consistent with the above statement. The ethtool_channels is always cleared by the caller, we just need to avoid setting the 'combined' fields. Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
