I think in theory this is the subsystem that DSL drivers would use, but there is only one driver for the "Solos ADSL2+". OpenWRT used to support the TI AR7 platform (later owned by Infineon, Lantiq, and Intel, now Maxlinear) with the "sangam-atm" driver for DSL, but that driver was never available in mainline Linux and is now gone from OpenWRT as well. It appears that the later hardware that is still supported uses a custom atm driver implementation rather than the in-kernel subsystem, using a different set of ioctls: https://git.openwrt.org/?p=openwrt/openwrt.git;a=tree;f=package/kernel/lantiq/ltq-atm/src There are also DSL SoCs from (at least) Broadcom, Realtek, Mediatek and Qualcomm, but no open source drivers, so I guess they probably all use their own kernel subsystems.
