This is required for Ethernet ADSL modems operating in 'Bridge' mode together with BSD Firewalls. (USB modems are not desirable as they are unreliable and their drivers are often released under restrictive licences) This is a growing issue in the UK and in other countries, where PPPoA is the standard used for ADSL authentication. FreeBSD firewalls are increasingly common and available to home users through the m0n0wall and pfSense projects. For reference, m0n0wall is based on FreeBSD 4.11 and pfSense on FreeBSD 6.0 HEAD. PPPoA authentication support is not present in the kernel of any FreeBSD release. In addition, almost all ADSL modems available in the UK support bridge mode, and so could be used with a FreeBSD firewall. Finally, Linux does have support for PPPoA authentication, but as usual it is in the form of an ugly and complex 'extension' to the current PPP software which is difficult to use. FreeBSD could again put itself ahead of the game by having a full BSD-licensed kernel-level implementation of RFC2364.
