[PATCH iwl-net v3 1/3] ice: fix asymmetric pause negotiation reporting in ethtool

[Aleksandr Loktionov <aleksandr.loktionov@intel.com>]

From: Tomasz Lichwala <tomasz.lichwala@intel.com>

Add Asym_Pause to the supported link modes so that asymmetric pause
negotiation is properly reported via ethtool. Without Asym_Pause in
the supported modes, 'ethtool -a' incorrectly shows 'RX/TX negotiated: off'
for asymmetric pause configurations, even when pause is properly
negotiated and functional at the hardware level.

Fixes: 5a056cd7ead2 ("ice: add lp_advertising flow control support")
