HP544+网卡的驱动设置
在 openERT 下使用 HP544+ 网卡的问题
总结
先说总结：尽量选择默认支持 mlx4-core 的 openwrt 固件，这样 HP544+ 网卡可以直接使用。
自行添加驱动非常的麻烦，而且未必能生效。
以下为历史记录，未能成功，留作存档。
处理过程
参考 https://www.snailium.com/server/home-server-improvement-virtualization.html 为 hp544+网卡安装驱动
opkg update
opkg install luci
opkg install kmod-mlx4-core
报错：cannot find dependency kernel for kmod-pps
原因是 openwrt 的 kernel 版本不够新，要求 5.15.86-1，可以通过 uname -a 命令来查看当前 kernel 版本。
参考：https://cloud.tencent.com/developer/article/2101934
打开页面 https://downloads.openwrt.org/snapshots/targets/x86/64/packages/，找到 kernel
wget https://downloads.openwrt.org/snapshots/targets/x86/64/packages/kernel_5.15.85-1-9f9e11a5e946333b83ba37f6864e5c49_x86_64.ipk
opkg install kernel_5.15.85-1-9f9e11a5e946333b83ba37f6864e5c49_x86_64.ipk
之后继续执行安装：
opkg update
opkg install luci
opkg install kmod-mlx4-core

执行 ip addr 命令发现还是无法识别网卡，继续：
opkg install kmod-mlx4-core_5.15.85-1_x86_64.ipk

网卡驱动已经安装，lspci 可以识别网卡，但是网卡一直无法识别。
后记
找了一个支持的固件就直接搞定了
