looks like i have successfully turned #GlasgowInterfaceExplorer (as well as an RTL8211FD devboard I got from Aliexpress) into a fairly decent network interface card :D
this applet is written idiomatically and with no modification of the core USB framework (using the abstractions every other applet is using, rather than direct access to libusb or something), in a single-threaded CPython 3.12 asyncio event loop
I think probably the most fun I have with it is throwing like a gigabit/s of UDP spam at it and watching @mwk's laptop (which uses it as the uplink) get essentially no jank in real-time applications like ssh
empirically, building a 10/100 MAC essentially from scratch, including a bunch of stream infrastructure, with Amaranth and Glasgow takes less than four days
@whitequark Was this intended as a tech demo, or to solve a specific real world problem? Or are you trying to design a [R]MII backend for glasgow just to have one?
@azonenberg intended to solve a specific real world problem of needing a NIC that can support 16K jumbo frames (which itself is a result of using Ethernet as a transport layer for what used to be an SCSI device)
@azonenberg and then @manawyrm told me that (paraphrased) i should not be solving bufferbloat that i got in the applet because it's hard, so i made the latency be under 10ms
