Until now the Wi-Fi bands were named after the first 802.11 standard
that introduced them: "a" for 5GHz introduced in 802.11a and "bg" for
2.4GHz introduced in 802.11b/g. With new bands added, this naming
scheme doesn't sound very intuitive to remember for users. Furthermore
we have now 6GHz that is introduced by 802.11ax (Wi-Fi 6), but the
compatible devices can use all three the bands (2.4, 5, 6 GHz).
For the 6 GHz band, simply name it "6GHz".

Parse the access point announced bandwidth in MHz. This is considering
both HT and VHT. Please notice that for VHT 80+80 MHz we are representing it
as 160 MHz.
We use clang-format for automatic formatting of our source files.
Since clang-format is actively maintained software, the actual
formatting depends on the used version of clang-format. That is
unfortunate and painful, but really unavoidable unless clang-format
would be strictly bug-compatible.
So the version that we must use is from the current Fedora release, which
is also tested by our gitlab-ci. Previously, we were using Fedora 34 with
clang-tools-extra-12.0.1-1.fc34.x86_64.
As Fedora 35 comes along, we need to update our formatting as Fedora 35
comes with version "13.0.0~rc1-1.fc35".
An alternative would be to freeze on version 12, but that has different
problems (like, it's cumbersome to rebuild clang 12 on Fedora 35 and it
would be cumbersome for our developers which are on Fedora 35 to use a
clang that they cannot easily install).
The (differently painful) solution is to reformat from time to time, as we
switch to a new Fedora (and thus clang) version.
Usually we would expect that such a reformatting brings minor changes.
But this time, the changes are huge. That is mentioned in the release
notes [1] as
Makes PointerAligment: Right working with AlignConsecutiveDeclarations. (Fixes https://llvm.org/PR27353)
