准备工作
固件我们直接去官网下载
# 官方的固件下载地址

# 刷固件需要用到的MFT工具

# 网卡驱动
https://network.nvidia.com/products/adapter-software/ethernet/windows/winof-2/华子的网卡固件在官网没办法下载，但是在超聚合官网可以下载
https://support.xfusion.com/support/#/zh/software-basics/d4b7de78-c4c0-46db-bbbd-98926e13e2da关于SP333和SP380这两个型号的华子官网介绍
# SP333是2*10GE SFP+，向下兼容1GE速率（使用10GE SFP+光模块）。
https://support.huawei.com/enterprise/zh/doc/EDOC1100198574/672e0978
# SP380是2*25GE SFP28，向下兼容10GE速率（使用10G SFP+光模块）。
https://support.huawei.com/enterprise/zh/doc/EDOC1100056515/c20b2897根据之前对MCX4网卡的了解，这两个应该就是MCX4121A-XCAT和MCX4121A-ACAT的OEM版本
https://network.nvidia.com/files/doc-2020/pb-connectx-4-lx-en-card.pdf
这里需要提前说一下结论，这里刷固件的时候分别刷入了mellanox官方的MCX4121A-ACAT固件和华为的SP380固件：
刷入mellanox官方固件的时候，网卡只有一个网口能正常识别到模块，另一个网口在系统中能看到网卡，但是无法识别线缆（手头的AOC和DAC都不行，换另一个网口则都正常），并且正常识别的网卡在win11中没办法正常通过DHCP获取IP（其他系统暂时没测试）
刷入华为的SP380固件的时候，网卡信息能正常识别，两个网口各项功能看起来正常。建议还是刷入华为的固件比较稳妥。
windows 刷机
刷机命令参考如下
flint --no_fw_ctrl -allow_psid_change -d {设备号} -i {文件路径(注:这里最好为根目录下,如不为根目录注意目录名中不要含有中文)} burn这里我用powershell执行的命令参考如下：
PS C:\Users\Mr7th\Desktop\NIC-SP380-CX4Lx-FW-14.31.1014> flint --no_fw_ctrl -allow_psid_change -d mt4117_pciconf0 -i .\fw-ConnectX4Lx-rel-14_31_1014_H_SP380-FlexBoot-3.6.403_4117_14_24_13_RELEASE_X64_AARCH64_20210706_VPD.bin burn
Done.
Current FW version on flash: 14.32.1900
New FW version: 14.31.1014
Note: The new FW version is older than the current FW version on flash.
Do you want to continue ? (y/n) [n] : y
You are about to replace current PSID on flash - "MT_2420110034" with a different PSID - "HUA0000000023".
Note: It is highly recommended not to change the PSID.
Do you want to continue ? (y/n) [n] : y
Burning FW image without signatures - OK
Restoring signature - OK
-I- To load new FW run mlxfwreset or reboot machine.刷固件需要等待挺长一段时间的，要有耐心，刷完之后我们使用mlxfwmanager命令检查当前固件信息

按下win+R键，输入ncpa.cpl进去管理界面查看网卡信息
可以看到这两个网卡都正常协商到了10G速率（只有10G交换机），并且都通过DHCP的方式正常获取到了IP、DNS等信息
也可以通过下面这两个命令来查看网卡的速率信息
