[RP-PPPoE] Which timeout affects PADO packets?

[Dan Jacobson]

Lessons learned: if users are having similar problems they should add a
sleep until there are no more mixing of kernel and pppd messages, like
there was here:

How long should this sleep be? Well in

in fact I used
sleep 20 #at 01:15:28
but as one sees the kernel was still printing out messages in the
background for two more seconds, so probably a sleep 3 or 4 will do.

I see, /usr/lib/pppd/2.4.7/rp-pppoe.so must have somewhat fewer options
than /usr/sbin/pppoe (which I still can't figure out how to use
directly, even though using pppd is fine already.)
