Update: Re: VIM1's wifi doesn't work after update to Linux 6.1

[Zhang Ning]

Hi, All

In previous emails, I heard WIFI works fine.

I asked Nick for their tree for linux-6.1.
(due to their tree have some package patches, which make fail to build
deb, I picked other patches)
here is my tree: https://github.com/zhangn1985/linux-stable.git

I build it in an arm64 chroot env (faster than real arm64 board), with below commands:
```
make kvims_defconfig
make bindeb-pkg -j`nproc`
```

install to my VIM1, connect it to WIFI router and run:
```
while true; do curl www.baidu.com; done
```

it stucks after 3mins, same logs shown in previous email.

here is my brcm firmware md5:
501ca4e8307ad8e71c32f0d24369bada  brcmfmac43455-sdio.bin
d3ad92472ef030c3897062ff809a9083  brcmfmac43455-sdio.txt

BR.
Ning.
