Bug Description
[Impact]
Future Pi Zero 2 boards will have a slightly different wifi chip on board which requires a variant of the current firmware. This is being added to the rename of linux-firmware-
[Test Plan]
Boards with the new wifi chip are not yet available, so the following test plan is the best we can do:
* Flash a fresh SD card with the appropriate server image
* Boot the card on the Pi under test with *no* ethernet attached (if the board supports it)
* Edit /etc/netplan/
* sudo netplan apply
* ip addr # verify wlan0 is up and has a valid address
* Enable -proposed and update
* sudo apt install linux-firmware-
* sudo reboot
* ip addr # verify wlan0 is up and has a valid address
This should be performed on all supported boards with wifi (3B, 3A+, 3B+, 4B, 400) on both supported architectures (armhf, and arm64).
[Regression Potential]
As we're updating the wifi firmware, the obvious possible regression is failure of the wifi interface (hence the testing of all supported boards in the plan).
[Original Description]
In the upstream wifi firmware package (version 1:20210315-3+rpt3 of the firmware-nonfree package), the following is noted in the changelog: "Future Zero 2 W boards will have an alternative version of 43436 that should have different firmware, named brcmfmac43436s-
