Subject: [PATCH V2 02/22] net-next: mediatek: fix gigabit and flow control advertisement
Date: Mon,  9 May 2016 12:03:54 +0200	[thread overview]
Message-ID: <1462788254-40572-3-git-send-email-john@phrozen.org> (raw)
In-Reply-To: <1462788254-40572-1-git-send-email-john@phrozen.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.
