When it's really advanced, yes. But here it's just about tunnel
bridging, which is a very common L2TP thing to do.

I wouldn't call

+ ret = ioctl(ppp_chan_fd, PPPIOCBRIDGECHAN, &chindx2);
+ close(ppp_chan_fd);
+ if (ret < 0)
+ return -errno;

documentation...

A more complete example, yes. I don't plan on taking time to do it.
