Calling ATM NIC users: en(4), fatm(4), hatm(4), patm(4)

there is a freebsd-atm mailing list (at least there used to be). Should have been sent there too.

On the topic: I'd say: remove it. As the one who wrote/refactored much of that stuff I get approximately one support request per year. The problem is, that I can't really help, since while I have all of that equipment still available, I don't have any time to do anything with it. So the entire ATM stack is basically unsupported.

Our current ATM stack supports a small number of NICs that were current in the late 90s[0].  None of them have been manufactured in a long time and while you can buy hatm(4) devices on e-bay, it's increasingly difficult to find a motherboard that will accept them.

I'd like to propose removing support for these NICs along with the remaining ATM stack in FreeBSD 12.  This will give any existing users a supported OS until at least September 30, 2021 per our published EOL date for FreeBSD 11.

Would removal on this schedule cause you realistic hardship?  If so, please let us know.
