Subject: [PATCH net-next v4 2/6] ice: fix ICE_AQ_VSI_Q_OPT_RSS_* register values
Date: Mon, 16 Oct 2023 09:49:33 -0600	[thread overview]
Message-ID: <20231016154937.41224-3-ahmed.zaki@intel.com> (raw)
In-Reply-To: <20231016154937.41224-1-ahmed.zaki@intel.com>

Fix the values of the ICE_AQ_VSI_Q_OPT_RSS_* registers. Shifting is
already done when the values are used, no need to double shift. Bug was
not discovered earlier since only ICE_AQ_VSI_Q_OPT_RSS_TPLZ (Zero) is
currently used.

Also, rename ICE_AQ_VSI_Q_OPT_RSS_XXX to ICE_AQ_VSI_Q_OPT_RSS_HASH_XXX
for consistency.
