If anyone has any objections, please let me know. =============== [ Upstream commit fb00bc2e6cd2046282ba4b03f4fe682aee70b2f8 ] The commit d3ab3ffd1d728d7ee77340e7e7e2c7cfe6a4013e (bonding: use rlb_client_info->vlan_id instead of ->tag) remove the rlb_client_info->tag, but occur some issues, The vlan_get_tag() will return 0 for success and -EINVAL for error, so the client_info->vlan_id always be set to 0 if the vlan_get_tag return 0 for success, so the client_info would never get a correct vlan id. We should only set the vlan id to 0 when the vlan_get_tag return error.
