配置基于MCTP over SMBus的Endpoint，参考：mctpd使用说明 | 文档中心 | openUBMC
CSR配置如下：
"Objects": {
"Chip_Mctp": {
"Address": 58,
"AddrWidth": 1,
"OffsetWidth": 1,
"WriteTmout": 100,
"ReadTmout": 100,
"HealthStatus": 0,
"DrvWriteDelay": 0
},
"Endpoint_1": {
"TargetEid": "${Slot} |> expr(100 + $1)",
"TargetPhyAddr": 29,
"MessageType": 4,
"MediumType": 2,
"RefChip": "#/Chip_Mctp"
},
"MctpBinding_1": {
"BmcSMBusEid": 8,
"BmcSMBusPhyAddr": 16
},
结果app.log报错：mctpd ERROR: mctp_engine.lua(306): set smbus ep failed. endpoint eid: 101, msg_type: 0
我理解这是set Endpoint EID失败，所以我想尝试打印出对应的收发报文数据进行分析
根据论坛内容我尝试了两种方法打印：
方法一：inject注入开启报文捕获
参考鲲鹏bmc调试网卡部件，如何开启打印协议通信报文 - Hardware SIG - openUBMC 论坛
注入两段代码：
local c_mctp_engine = require 'mctp_engine'
local mctp_engine = c_mctp_engine.new()
mctp_engine:enable_pcie_capture()
local c_mctp_mdb_mgmt = require 'mctp_mdb_mgmt'
local mctp_mdb_mgmt = c_mctp_mdb_mgmt.new()
mctp_mdb_mgmt:reinit_all_smbus_ep()
获取app.log相关日志：

但是捕获的报文都是PCIe capture，似乎没有SMBus capture的内容
方法二：mdbctl的tracemctp
【已评审】Endpoint新增调试时打印报文功能 - Interface SIG / Interface评审 - openUBMC 论坛
参考此贴，用法为：tracemctp [ObjectName] [Action]，但实际只能输入tracemctp [Action]
注入mctp_mdb_mgmt:reinit_all_smbus_ep()后mdbctl还是看不到任何报文打印
而且lsprop会报错：
% lsobj Endpoint
Endpoint_0101010301_29_4
% lsprop Endpoint_0101010301_29_4
BMC.Error.Unknow: table: 0x64d04832e990
想问一下，怎么才能打印出MCTP over SMBus的通信报文
