The conflict resolution I intended (not the one you came up with) is described in the commit message of patch 589918df9322 ("net: dsa: sja1105: be stateless with FDB entries on SJA1105P/Q/R/S/SJA1110 too").

Hi all, Today's linux-next merge of the net-next tree got a conflict in: drivers/net/dsa/sja1105/sja1105_main.c between commit: 589918df9322 ("net: dsa: sja1105: be stateless with FDB entries on SJA1105P/Q/R/S/SJA1110 too") from the net tree and commit: 0fac6aa098ed ("net: dsa: sja1105: delete the best_effort_vlan_filtering mode") from the net-next tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. +++ b/drivers/net/dsa/sja1105/sja1105_main.c @@@ -1445,23 -1474,25 +1499,29 @@@ int sja1105pqrs_fdb_add(struct dsa_swit /* Search for an existing entry in the FDB table */ l2_lookup.macaddr = ether_addr_to_u64(addr); l2_lookup.vlanid = vid; - l2_lookup.iotag = SJA1105_S_TAG; l2_lookup.mask_macaddr = GENMASK_ULL(ETH_ALEN * 8 - 1, 0); - l2_lookup.mask_vlanid = VLAN_VID_MASK; + if (priv->vlan_aware) { + l2_lookup.mask_vlanid = VLAN_VID_MASK; + l2_lookup.mask_iotag = BIT(0); + } else { + l2_lookup.mask_vlanid = 0; + l2_lookup.mask_iotag = 0; + } l2_lookup.destports = BIT(port); + tmp = l2_lookup; + rc = sja1105_dynamic_config_read(priv, BLK_IDX_L2_LOOKUP, - SJA1105_SEARCH, &l2_lookup); - if (rc == 0) { - /* Found and this port is already in the entry's + SJA1105_SEARCH, &tmp); + if (rc == 0 && tmp.index != SJA1105_MAX_L2_LOOKUP_COUNT - 1) { + /* Found a static entry and this port is already in the entry's * port mask => job done */ - if (l2_lookup.destports & BIT(port)) + if ((tmp.destports & BIT(port)) && tmp.lockeds) return 0; + + l2_lookup = tmp; + /* l2_lookup.index is populated by the switch in case it * found something. */ @@@ -1536,8 -1537,15 +1596,14 @@@ int sja1105pqrs_fdb_del(struct dsa_swit l2_lookup.macaddr = ether_addr_to_u64(addr); l2_lookup.vlanid = vid; - l2_lookup.iotag = SJA1105_S_TAG; l2_lookup.mask_macaddr = GENMASK_ULL(ETH_ALEN * 8 - 1, 0); - l2_lookup.mask_vlanid = VLAN_VID_MASK; + if (priv->vlan_aware) { + l2_lookup.mask_vlanid = VLAN_VID_MASK; + l2_lookup.mask_iotag = BIT(0); + } else { + l2_lookup.mask_vlanid = 0; + l2_lookup.mask_iotag = 0; + } l2_lookup.destports = BIT(port); rc = sja1105_dynamic_config_read(priv, BLK_IDX_L2_LOOKUP,
