From: Vladimir Oltean Date: Sat, 9 Nov 2019 13:02:55 +0000 (+0200) Subject: net: mscc: ocelot: limit vlan ingress filtering to actual number of ports X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=714d0ffabeb21550895ff32a8ba8866b684b5203;p=linux.git net: mscc: ocelot: limit vlan ingress filtering to actual number of ports The VSC7514 switch (Ocelot) is a 10-port device, while VSC9959 (Felix) is 6-port. Therefore the VLAN filtering mask would be out of bounds when calling for this new switch. Fix that. Signed-off-by: Vladimir Oltean Signed-off-by: David S.
