From: Mateusz Palczewski mateusz.palczewski@intel.com Date: Mon, 4 Jan 2021 15:00:02 +0000 Subject: [PATCH] i40e: Added Asym_Pause to supported link modes
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).
