Subject: [PATCH v1 net-next 3/5] net: dsa: mv88e6xxx: Refactor egress rate limiting
Date: Sat, 3 Dec 2016 04:45:18 +0100 [thread overview]
Message-ID: <1480736720-12608-4-git-send-email-andrew@lunn.ch> (raw)
In-Reply-To: <1480736720-12608-1-git-send-email-andrew@lunn.ch>
There are two different rate limiting configurations, depending on the
switch generation. Refactor this into ops.
