Re: Proposal to remove driver for the Cabletron EA41x SCSI Ethernet adapter
Hi, We have a driver for this device in sys/dev/scsipi/if_se.c. It was pretty popular with the pc532 crowd back in the day because SCSI was the only expansion bus the pc532 had. There are changes coming to the network stack and it's unlikely that (a) anyone has such a device to test it, and (b) that the driver even works currently because it's been so long since probably anyone ran this code. I propose we remove this driver. If it's not too much work, it might be worth keeping because some newer hardware will emulate it: https://hackaday.io/project/18974-tiny-scsi-emulator If this is the same chip as is in the DaynaPort SCSI-Link-T, I can offer to test the driver.

I am sure many improvements are need to be made, but I am happy that I can record videos again if I need to! -- Kind regards, Yorick Hardy

Just a side note that I keep forgetting to mention: I used ffmpeg and oss to record videos over the last few years and "it used to work fine". I think that the most recent audio changes have broken some expectations that ffmpeg has, but it used to work (more or less) as ffmpeg expected. That said, I think a netbsd audio backend would be great. I will create a pkgsrc-wip package in the mean time to start working on a netbsd audio backend, unless someone beats me to it! [wip/ags also has some audio problems, it uses allegro for audio; but I will start another thread about that one day.] -- Kind regards, Yorick Hardy

But you're supposed to do short enough reads and writes that it shouldn't matter. That might be the cause of the worst of the problems. Do you want to work on this together somewhere?
