Robin H. Johnson dfd42d1393 net/ethtool: official interface for changing ethtool params (bug #195479)
Implement a consistent interface for changing ethtool parameters, as
suggested in bug 195479. All variable names are based on the long option
to ethtool to set each group of parameters. Multiple entries seperated
by newlines are permitted for variable values.
