Hi Dave,
This patchset by Jenny adds sanity checks in ethtool ringparam
operation for input upper bounds, similarly to what's done in
ethtool_set_channels.
The checks are added in patch 1, using a call to get_ringparam
prior to calling set_ringparam NDO.
Patch 2 changes the function's behavior in mlx4_en, so that
it returns an error for out-of-range input, instead of rounding
it to closest valid, similar to mlx5e.
Patch 3 removes the upper bound checks in mlx5e_ethtool_set_ringparam
as it becomes redundant.

Thanks,
