Subject: Re: [PATCH net] net: dsa: mv88e6xxx: Fix counting of ATU violations

From: Andrew Lunn <>
Date: Wed,  6 Feb 2019 00:02:58 +0100

> The ATU port vector contains a bit per port of the switch. The code
> wrongly used it as a port number, and incremented a port counter. This
> resulted in the wrong interfaces counter being incremented, and
> potentially going off the end of the array of ports.
> Fix this by using the source port ID for the violation, which really
> is a port number.
