Subject: net: realtek: r8169: implement set_link_ksettings()
From: Tobias Jakobi <tjakobi@xxxxxxxxxxxxxxxxxxxxx>
[ Upstream commit 9e77d7a5549dc4d4999a60676373ab3fd1dae4db ]
Commit 6fa1ba61520576cf1346c4ff09a056f2950cb3bf partially
implemented the new ethtool API, by replacing get_settings()
with get_link_ksettings(). This breaks ethtool, since the
userspace tool (according to the new API specs) never tries
the legacy set() call, when the new get() call succeeds.
All attempts to chance some setting from userspace result in:
> Cannot set new settings: Operation not supported
Implement the missing set() call.
