Subject: [Intel-wired-lan] [PATCH net-next] ice: return proper error code in ice_add_adv_rule
Date: Fri,  1 Apr 2022 11:59:58 +0200	[thread overview]
Message-ID: <20220401095958.438230-1-wojciech.drewek@intel.com> (raw)

When number of words exceeds ICE_MAX_CHAIN_WORDS, -ENOSPC
should be returned not -EINVAL. Do not overwrite this
error code in ice_add_tc_flower_adv_fltr.
