sfc
记得 sfc 有两个常用工具
[root@test01 22:01:52 ]$ sfboot -i p2p2_0 --repair^C
[root@test01 22:02:19 ]$ sfupdate --write
Solarflare firmware update utility [v8.2.4]

似乎只有这样，才可以配置 sriov ，不然 sriov 在 sysfs 下，连目录都没有:
sfboot --adapter=ens2f1np1 switch-mode=sriov pf-count=1 vf-count=120
基本的调试方法
echo “0000:00:0a.0” | sudo tee /sys/bus/pci/drivers/sfc/bind echo “module sfc +p” > /sys/kernel/debug/dynamic_debug/control

主线内核 sfc 驱动和 onload sfc 驱动有一个关键区别，
主线内核是在探测驱动的时候调用到 efx_mcdi_alloc_vis ， 而 onload 中是 ip link set dev ens10 up 的时候调用 efx_mcdi_alloc_vis
