net-dialup/ppp renamed the plugin to pppoe.so to avoid conflicts with net-dialup/rp-pppoe. This was an upstream change. ```commit 610a7bd76eb1f99f22317541b35001b1e24877ed Author: pali <7141871+pali@users.noreply.github.com> Date: Fri Jul 30 05:29:01 2021 +0200 pppoe: Remove rp-pppoe.so symlink to not conflict with real rp-pppoe.so plugin (#304) Backward compatibility symlink is there already for one ppp release. Remove it for next ppp release to not conflict with real rp-pppoe.so plugin. So both ppp's pppoe.so and rp's rp-pppoe.so plugins can be installed together. Now when conversion to automake was done, it is a good time to drop this problematic symlink from default installation. Signed-off-by: Pali Rohár <pali@kernel.org> ``` If you *really* want (or need) the rp-pppoe plugin version, merge >=net-dialup/rp-pppoe-3.15-r1. I would state that the pppoe.so that ships with pppd is just fine, it was (from what I can infer) forked from the original rp-pppoe.so plugin anyway. rp-pppoe package seems like a one-person show at this point, with myself possibly being the only other submitter of patches (infrequent) at this stage. The ONLY component from rp-pppoe package which in my opinion is really still needed is the server component. If there is documentation stating that pppoe connections should set plugin rp-pppoe.so then we better fix that to just state plugin pppoe.so Possibly (probably) net-misc/networkmanager needs some fixing to reference pppoe.so instead of rp-pppoe.so? Specifically: src/core/ppp/nm-ppp-manager.c requires s/rp-pppoe/pppoe/ to be actioned against it from what I've read of the code. I don't use networkmanager so cannot assist beyond that. Towards that, I'm also dropping myself from CC. I do not believe any changes to net-dialup/ppp nor net-dialup/rp-pppoe is required. It's networkmanager that should be fixed. I'm marking this to confirmed due to code inspection.
