hello, I use a 3Com ADSL Modem HomeConnect. 3Com made something really stupid, the modem do not comply with PPPoE RFC standards in discovery packet. Under FreeBSD, there is an option to tell the system that we use this modem, but under OpenBSD I can't find this feature.
So I tried to bypass pppoe included in OpenBSD and install rp-pppoe (since it also exists an option in rp-pppoe to deal with 3Com ADSL modems) but it doesn't work since it needs pppd 2.3.7 at least, and OpenBSD 3.7 provides 2.3.5. What I try to do now, is to modify OpenBSD pppoe behaviour to work fine with this modem. Do you know how I can modify (and where) the discovery packet value in source code under OpenBSD ?
