Hi Bruce, I have added support for both Rx (strip) and Tx (insertion) for QinQ. net/iavf: support QinQ strip net/iavf: support QinQ insertion Earlier only 0x8100 was supported partially. These commits add 0x88a8 as well as tightens 0x8100. Thanks, Anurag > > > > * **Updated Intel ice driver.** > > > > -- > > 2.34.1 > >
