It's actually ppoa - BUT - all that is handled by the DSL modem. I have private IPs. I had a WinME machine doing something, I had this machine doing something, and my other BSD machine was performing a DL from an FTP site in Europe or possibly to one of my servers. [My DSL is 512Kb down while the servers I admin are 100Mbit uplinks into an OC192 backbone and I often DL to there and then just perform a final transfer to here as I contol both ends of the link and and wont have delays/timeouts] The machine with the FTP got the no buffer space available and it and this machine are running 4.4. This machine was just recently reloaded with 4.4 from CD as I stupidly trashed my HD by accident. Since the machine that died was performing pure IP to IP [as it looked to itself] there was no pppoe involved. Bringing the interface down and backup fixed it.
