Date: Thu, 20 Jun 2024 08:55:55 -0400 Message-ID: <20240620125601.15755-2-aconole@redhat.com> In-Reply-To: <20240620125601.15755-1-aconole@redhat.com> References: <20240620125601.15755-1-aconole@redhat.com> Precedence: bulk X-Mailing-List: linux-kselftest@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-Scanned-By: MIMEDefang 3.0 on 10.30.177.15 The OVS module can operate in conjunction with various types of tunnel ports. These are created as either explicit tunnel vport types, OR by creating a tunnel interface which acts as an anchor for the lightweight tunnel support. This patch adds the ability to add tunnel ports to an OVS datapath for testing various scenarios with tunnel ports. With this addition, the vswitch "plumbing" will at least be able to push packets around using the tunnel vports. Future patches will add support for setting required tunnel metadata for lwts in the datapath. The end goal will be to push packets via these tunnels, and will be used in an upcoming commit for testing the path MTU.

Date: Thu, 20 Jun 2024 08:55:58 -0400 Message-ID: <20240620125601.15755-5-aconole@redhat.com> In-Reply-To: <20240620125601.15755-1-aconole@redhat.com> References: <20240620125601.15755-1-aconole@redhat.com> Precedence: bulk X-Mailing-List: linux-kselftest@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-Scanned-By: MIMEDefang 3.0 on 10.30.177.15 This will be used when setting details about the tunnel to use as transport. There is a difference between the ODP format between tunnel(): the 'key' flag is not actually a flag field, so we don't support it in the same way that the vswitchd userspace supports displaying it.
