ethtool: change ethtool_set_gro() to use ethtool_op_get_rx_csum
To be able to switch on GRO on a device, ethtool_set_gro() checks this
device provides a get_rx_csum() method.
Some devices dont provide this method, while they do support RX
checksumming.
This patch allows bonding to support GRO :
ethtool -K bond0 gro on
