^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) ATM is a high-speed networking technology for Local Area Networks
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) and Wide Area Networks. It uses a fixed packet size and is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) connection oriented, allowing for the negotiation of minimum
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) bandwidth requirements.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) In order to participate in an ATM network, your Linux box needs an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) ATM networking card. If you have that, say Y here and to the driver
