[ Upstream commit 71891e2dab6b55a870f8f7735e44a2963860b5c6 ]
In kernel log ths message appears on every boot: "warning: `NetworkChangeNo' uses legacy ethtool link settings API, link modes are only partially reported"
When ethtool link settings API changed, it started complaining about usages of old API. Ironically, the original patch was from google but the application using the legacy API is chrome.
Linux ABI is fixed as much as possible. The kernel must not break it and should not complain about applications using legacy API's. This patch just removes the warning since using legacy API's in Linux is perfectly acceptable.
