Subject: [PATCH V3 2/4] net-next: mediatek: fix gigabit and flow control advertisement
Date: Tue, 10 May 2016 07:08:39 +0200 [thread overview]
Message-ID: <1462856921-27441-3-git-send-email-john@phrozen.org> (raw)
In-Reply-To: <1462856921-27441-1-git-send-email-john-Pj+rj9U5foFAfugRpC6u6w@public.gmane.org>
The current code will not setup the PHYs advertisement features correctly.
Fix this and properly advertise Gigabit features and properly handle
asymmetric pause frames.
