ethtool: trim policy tables
Since ethtool uses strict attribute validation there's no need to initialize all attributes in policy tables. 0 is NLA_UNSPEC which is going to be rejected. Remove the NLA_REJECTs. Similarly attributes above maxattrs are rejected, so there's no need to always size the policy tables to ETHTOOL_A_..._MAX. v2: - new patch Suggested-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.
