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).
Fixes: 4e91bcd5d47a ("i40e: Finish implementation of ethtool get settings")
