If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 855e899e956b50f377dd55688c32a41942e3ec13 Author: Mateusz Palczewski <mateusz.palczewski@xxxxxxxxx> Date: Mon Jan 4 15:00:02 2021 +0000 i40e: Added Asym_Pause to supported link modes [ Upstream commit 90449e98c265296329446c7abcd2aae3b20c0bc9 ] Add Asym_Pause to supported link modes (it is supported by HW). Lack of Asym_Pause in supported modes can cause several problems, i.e. it won't be possible to turn the autonegotiation on with asymmetric pause settings (i.e. Tx on, Rx off).
