[Solved] Wifi device not showing in ip link

Hi, I did a brand new install of Arch. In the installer, when I did `ip link`, it showed devices `lo` and my `wlan0`... But now when I'm done with the installation and I've booted up, it only shows the `lo` device, and I cannot connect to the internet. I'll try to provide some debug information.

Kernel version: `5.16.14-arch-1`

It shows my device when I do `lspci`... It's `Ethernet controller: Marvell Technology Group Ltd. 88W8897 [AVASTAR] 802.11ac Wireless`
When I do `lspci -k`, this is the output:
```
01:00.0 Ethernet controller: Marvell Technology Group Ltd. 88W8897 [AVASTAR] 802.11ac Wireless
        Kernel driver in use: mwifiex_pcie
        Kernel modules: mwifiex_pcie
```

Ip link only shows the device `lo`, but when I was in archiso it showed `lo` and `wlan0` and I could connect via iwctl.

That's a marvell card which is one of the firmwares that got split into a subpackage in https://archlinux.org/news/linux-firmwa … splitting/ you need to install the linux-firmware-marvell package in addition to the standard linux-firmware
