Zero the statistics counters when setting up the global registers. Otherwise the counters will remain from the last boot if the power has not been removed. Signed-off-by: Andrew Lunn <andrew@lunn.ch> --- This patch will only cleanly apply after the debug series. There is no actual dependency, so applying the patch with some fuzz will allow it to be applied without the debug series. drivers/net/dsa/mv88e6xxx.c | 6 ++++++ 1 file changed, 6 insertions(+)
