[9fans] missing /net/etherU0 on 9front rpi3

When I'm testing tailscale on 9front/arm64 on rpi3, something strange happened:
From the day I set up my rpi to be a cpu server till like an hour before, I'm pretty sure the ethernet card is shown as /net/etherU0.
However, for some reason, after one fshalt -r, /net/etherU0 disappeared. What's weird is that I can still connect to rpi using drawterm from my linux laptop in the same lan network.
After some digging I found out that it may caused by some firmware missing, so I downloaded brcmfmac43430-sdio.bin      brcmfmac43430-sdio.txt and put them under /lib/firmware.
(well before reboot I tried lc '#l0' so I'm sure that these firmware met the driver's needs)
After my reboot, the network card this time showed as /net/ether0.
This didnt affect too much, since I can now connect to internet from 9front. But when I ran tailscaled, it insisted to check /net/etherU0 and complained about it's non existence.

My current workaround is simply:

aux/stub -d /net/etherU0
bind /net/ether0 /net/etherU0

This solved the issue, and now I can connect to my tailscale subnet from rpi, and can use drawterm to connect to it through tailscale from my phone(so tailscale does work)

But the missing /net/etherU0 is just...so weird. Does anyone has any clues?

btw this is the tailscaled error log:
 netmon.New: route ip+net: open /net/etherU0/addr: dns: file does not exist: '/net/etherU0'

tried
the result is in my first post
in brief /net/etherU0 doesnt exist, but /net/ether0 exist, tailscaled insist to use /net/etherU0 so I have to bind
(however /net/etherU0 existed before, and it broke for some reason idk)
