Date: Thu, 21 Dec 2023 14:02:06 -0800 Message-Id: <20231221220218.197386-2-michael.chan@broadcom.com> X-Mailer: git-send-email 2.32.0 In-Reply-To: <20231221220218.197386-1-michael.chan@broadcom.com> References: <20231221220218.197386-1-michael.chan@broadcom.com> Precedence: bulk X-Mailing-List: netdev@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-Patchwork-Delegate: kuba@kernel.org This is in preparation to support user defined L2 (ether) filters, which will have many similarities with ntuple filters. Refactor bnxt_ntuple_filter structure to have a bnxt_filter_base structure that can be re-used by the L2 filters.
