Check for ethtool_ops structures that are only stored in the ethtool_ops
field of a net_device structure or passed as the second argument to
netdev_set_default_ethtool_ops. These contexts are declared const, so
ethtool_ops structures that have these properties can be declared as const
also.

ethtool_ops has attributes in sub struct ethtool_coalesce that
correspond to the parameters intagg_delay and dynamic_intagg. It is
preferable to set these properties with ethtool rather than
module_param, so create these attributes in adapter and set them using
ethtool_coalesce's rx_coalesce_usecs and rx_use_adaptive_coalesce.
