Date: Tue, 9 Mar 2021 04:16:53 +0200 From: Vladimir Oltean <olteanv@...il.com> To: "David S . Miller" <davem@...emloft.net>, Jakub Kicinski <kuba@...nel.org>, netdev@...r.kernel.org Cc: Florian Fainelli <f.fainelli@...il.com>, Andrew Lunn <andrew@...n.ch>, Vivien Didelot <vivien.didelot@...il.com>, Kurt Kanzenbach <kurt@...utronix.de>, Tobias Waldekranz <tobias@...dekranz.com>, Vladimir Oltean <vladimir.oltean@....com> Subject: [RFC PATCH net 0/4] Clear rx-vlan-filter feature in DSA when necessary From: Vladimir Oltean <vladimir.oltean@....com> This is a proposal for an alternative solution to the problems presented by Tobias here: https://patchwork.kernel.org/project/netdevbpf/cover/20210308150405.3694678-1-tobias@waldekranz.com/ The key difference is that his patch series makes dsa_slave_vlan_rx_add_vid accept -EOPNOTSUPP and silently transforms it into an error code of 0, while my patch series avoids calling dsa_slave_vlan_rx_add_vid when it is not needed. Note that the series applies on top of this other bugfix: https://patchwork.kernel.org/project/netdevbpf/patch/20210308135509.3040286-1-olteanv@gmail.com/ Vladimir Oltean (4): net: dsa: on 'bridge vlan add', check for 8021q uppers of all bridge ports net: dsa: prevent hardware forwarding between unbridged 8021q uppers net: dsa: don't advertise 'rx-vlan-filter' if VLAN filtering not global net: dsa: let drivers state that they need VLAN filtering while standalone drivers/net/dsa/hirschmann/hellcreek.c | 1 + include/net/dsa.h | 3 + net/dsa/dsa_priv.h | 8 +- net/dsa/port.c | 60 ++++++++++++++- net/dsa/slave.c | 100 ++++++++++++++++++++----- net/dsa/switch.c | 20 +++-- 6 files changed, 164 insertions(+), 28 deletions(-) -- 2.25.1
