From the +software dataplane, the netfilter infrastructure uses the dsa slave +devices to refer to the input and output device for the given skbuff. +Similarly, the flowtable definition in the ruleset refers to the dsa +slave port devices. + +This patch adds the glue code to call ndo_setup_tc with TC_SETUP_FT +with the master device via the dsa slave devices. + +Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> +--- + +--- a/net/dsa/slave.c ++++ b/net/dsa/slave.c +@@ -1202,14 +1202,32 @@ static int dsa_slave_setup_tc_block(stru + } + } + ++static int dsa_slave_setup_ft_block(struct dsa_switch *ds, int port, ++ void *type_data) ++{ ++ struct dsa_port *cpu_dp = dsa_to_port(ds, port)->cpu_dp; ++ struct net_device *master = cpu_dp->master; ++ ++ if (!master->netdev_ops->ndo_setup_tc) ++ return -EOPNOTSUPP; ++ ++ return master->netdev_ops->ndo_setup_tc(master, TC_SETUP_FT, type_data); ++} ++ + static int dsa_slave_setup_tc(struct net_device *dev, enum tc_setup_type type, + void *type_data) + { + struct dsa_port *dp = dsa_slave_to_port(dev); + struct dsa_switch *ds = dp->ds; + +- if (type == TC_SETUP_BLOCK) ++ switch (type) { ++ case TC_SETUP_BLOCK: + return dsa_slave_setup_tc_block(dev, type_data); ++ case TC_SETUP_FT: ++ return dsa_slave_setup_ft_block(ds, dp->index, type_data); ++ default: ++ break; ++ } + + if (!ds->ops->port_setup_tc) + return -EOPNOTSUPP; |
