From ef70b1119ee8e788f7f4ac22fe1f016363d7921f Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 3 Dec 2016 04:45:18 +0100 Subject: [PATCH] net: dsa: mv88e6xxx: Refactor egress rate limiting There are two different rate limiting configurations, depending on the switch generation. Refactor this into ops. Signed-off-by: Andrew Lunn Signed-off-by: David S.
