[RP-PPPoE] Which timeout affects PADO packets?

[Dan Jacobson]

DS> If you run the pppoe executable, it's the "-t" option.

OK I put a -t 60 into
# pppd default-asyncmap defaultroute lcp-echo-failure 7 \
  lcp-echo-interval 50 mtu 1492 noaccomp noauth noipdefault noproxyarp \
  persist plugin rp-pppoe.so usepeerdns user xxx at hinet.net pty \
  'pppoe -I nic-enp7s0 -T 80 -t 60 -m 1452' nic-enp7s0 debug

00:56:54 pppd[1769]: Recv PPPOE Discovery V1T1 PADO session 0x0 length 22

which didn't change anything, and
$ man pppoe
SYNOPSIS
       pppd pty 'pppoe [pppoe_options]' [pppd_options]
       pppoe -A [pppoe_options]

seems to rule out any direct running of the pppoe executable other than with -A.

So how would I run the pppoe executable? Thanks.
