My hope is to sync up with the openwrt final from a binary perspective.

There are about 12 of cerowrt's more experimental patches missing from
openwrt beta - notably one that speeds up ivp6 a  lot. there are also
some experimental variants of fq_codel in there. There's a change to
wireless diffserv behavior. There's a patch reducing buffering on the
ath9k (but I think that's in openwrt too)

the debloat package runs all interfaces, turning off various offloads,
and enabling fq_codel on all interfaces.

It is kind of my hope more folk try running the debloat package on
openwrt AA final, rather than trying to run cerowrt as their main
router.

cerowrt has these usb-serial packages built. They are used by gpsd among others.

You can see the package list in the relevant release's package directory.
