Subject: [PATCH net-next] liquidio: support use of ethtool to set link speed
of CN23XX-225 cards
From: Weilin Chang <weilin.chang@...ium.com>
Support setting the link speed of CN23XX-225 cards (which can do 25Gbps or
10Gbps) via ethtool_ops.set_link_ksettings.
Also fix the function assigned to ethtool_ops.get_link_ksettings to use the
new link_ksettings api completely (instead of partially via
ethtool_convert_legacy_u32_to_link_mode).
