===PPPoE===
*Linux is capable of supporting RFC 4638 for an MTU of 1500 (or greater) over PPPoE
**This is supported on BT FTTC▼
**Kernel 2.6.34 is required to fix bugs with certain network cards and non-linear SKBs (ea8420e9, 19937d04)▼
**pppd 2.4.6 is required for RFC 4638 support (this is in git but not yet released)▼
▲This is supported on BT FTTC
This was reported in IRC on Feb 6th 2011. If you get people saying their line didn't come back or their linux box crashed (as in kernel oopsed) after a blip, turns out there's a bug in the kernel pppoe code for 2.6.36 which has been hitting me. some kind of double free in the disconnect code causes a kernel panic. there's a patch here: http://kerneltrap.org/mailarchive/linux-kernel/2010/12/3/4654538 which seems to work for me▼
