[PATCH 5.11 116/210] i40e: Added Asym_Pause to supported link modes

[Greg Kroah-Hartman]

From: Mateusz Palczewski <mateusz.palczewski@xxxxxxxxx>

[ 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).

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