Subject: [PATCH iwl-next 6/6] i40e: Initialize hardware capabilities at single place
Date:   Fri, 20 Oct 2023 21:37:42 +0200
Message-ID: <20231020193746.2274379-6-ivecera@redhat.com>
In-Reply-To: <20231020193746.2274379-1-ivecera@redhat.com>
References: <20231020193746.2274379-1-ivecera@redhat.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Some i40e_hw.caps bits are set in i40e_set_hw_caps(), some of them
in i40e_init_adminq() and the rest of them in i40e_sw_init().
Consolidate the initialization to single proper place i40e_set_hw_caps().
