I believe PPPoE over BR2684 is also used on ADSL lines. https://git.kernel.org/torvalds/c/ae088d663bee strongly seems to imply that I used to use it myself, or at least was *able* to switch to it for testing (although I could have sworn I mostly used PPPoA). > - net/atm/lec.c - LAN Emulation Client (LANE) > - net/atm/mpc.c, mpoa_caches.c, mpoa_proc.c - Multi-Protocol Over ATM > > Removed PCI/SBUS ATM device drivers (drivers/atm/): > - adummy, atmtcp - software/testing ATM devices > - eni - Efficient Networks ENI155P (OC-3, ~1995) > - fore200e - FORE Systems 200E PCI/SBUS (OC-3, ~1999) > - he - ForeRunner HE (OC-3/OC-12, ~2000) > - idt77105 - IDT 77105 25 Mbps ATM PHY > - idt77252 - IDT 77252 NICStAR II (OC-3, ~2000) > - iphase - Interphase ATM PCI (OC-3/DS3/E3) > - lanai - Efficient Networks Speedstream 3010 > - nicstar - IDT 77201 NICStAR (155/25 Mbps, ~1999) > - solos-pci - Traverse Technologies ADSL2+ PCI (defunct vendor) Traverse still exists: https://traverse.com.au/ I suspect they don't have a huge amount of interest in the Solos any more, or the Geode-based SBC they sold with two of them on-board. But OpenWrt does still support them, and I even have one here (although no ADSL line to test it with). They were briefly popular as fully Linux- supported ADSL routers.
