Hi David,
which drivers have you incorporated into usbnet?
Only the ones that there now. The "recent" additions have been the Zaurus models, and CDC Ethernet.
David Hollis has also started to look at merging in the ax8817x support, net saving about 1500 LOC (his estimate) and gaining various features, but that's not usable yet.
If very many drivers start to build on that same core framework -- which I think is probably very reasonable, since the critical "bulk queueing" paths are almost identical -- we'll want to be able to modularize the "minidrivers" on top of taht core, much like Greg did with usb-serial.
More specifically is catc.c worth fixing with respect to dma coherency?
I'm not sure what you mean. It could avoid memcpy() and do DMA right from the skb data, but that's not in itself a dma coherency issue.
