> Subject: [Intel-wired-lan] [PATCH iwl-net v1 2/3] igc: use EOPNOTSUPP
> instead of ENOTSUPP in igc_ethtool_get_sset_count()
>
> igc_ethtool_get_sset_count() returns -ENOTSUPP when a given stringset
> is not supported, causing userland programs to get "Unknown error
> 524".
>
> Since EOPNOTSUPP should be used when error is propagated to userland,
> return -EOPNOTSUPP instead of -ENOTSUPP.
