           Summary: Please consider adding possibility to have multiple
                    PPPoE sessions with different MAC addresses

This wishlist item is mostly relevant to German users. In Germany, Deutsche Telekom has a near monopoly regarding DSL connections to residential homes. They are, however, required, to resell their network to other ISPs which has led to a rather interesting combination of Internet tariffs and feature sets available via Deutsche Telekom T-DSL connections. Technical Basis for the T-DSL customer interface is PPPoE over a bridged ATM session, so it is technically possible to have multiple PPPoE sessions on the same line, allowing concurrent use of more than a single ISP which might be interesting with special interest services like streaming, fixed IP address and/or flat rate. However, Deutsche Telekom technically forbids multiple PPPoE sessions originating from a single MAC address, so one needs multiple network interfaces to originate the PPPoE sessions from. Sven Geggus has a patch against rp-pppoed, which allows to fake the sending MAC address for additional PPPoE sessions, circumventing the artificially introduced limitation of the T-DSL connection. The patch is available on http://geggus.net/sven/rp-pppoe-fakemac.diff Please consider adding that possibility to the kernel PPPoE code as well. Greetings Marc
