I could plug tninkpad into the gl-ar750 LAN port to dogfood the wired
networking

Apparently we're not currently doing anything special with busybox,
just using the default nixos build with the default applets.
We'd like to be able to say in modules which applets they need,
so that we build all necessary applets but don't waste any space.
But we don't want to build a busybox for each module because that
would be a big waste of space.
One option:
- add busybox configuration to `config` so that modules can maul it
- add a busybox module that builds it with union of all config and
adds link in /bin
- make everything else look in /bin instead of referencing pkgs.busybox
It would be good if services could assert somehow that their required
config is present

We have ath9k listening for packets. To make this ready to use:
- need to load the modules
- enable bridging lan with wlan
- packet forwarding
- firewall

need to fix all the other broken ci jobs :-(
The wlan test is failing because we moved mac80211 to a module and
there's nothing running to insmod it

bridge is e2b3738d0f8c3f2fd76ebcef65612de502a7b121 but it's the wrong
way around: the master interface needs to be up whether or not all
of its children are, so members depend on master not vice versa
Next steps:
- re-implement bridge, enable bridging lan with wlan
- packet forwarding
- firewall
- ath10k
- ipv6

bridging wlan was made complex because can't add a device to a bridge
until it's operational, and wlan0 is not operational until hostapd
has churned awhile. Therefore, "waitup" listens for netlink messages
and notifies s6 readiness stuff
we have a firewall nft script but we're not running it on boot
we have forwarding but no dns, maybe because we haven't told
dnsmasq about any upstream servers
