FWIW I had to add this to /etc/config/network (done via luci actually):
option keepalive '500 30'

Otherwise it uses these default values from /etc/ppp/options, and then I hit: https://dev.openwrt.org/ticket/7793:
lcp-echo-failure 5
lcp-echo-interval 1

The symptomps are that if I start a large download after half a minute or so pppd complains that it didn't receive reply to 5 LCP echo packets and disconnects/reconnects.
Sounds like the LCP echo/reply packets should get prioritized, but I don't know if it is my router that is dropping them or my ISP.

When you tested PPPoE did you notice pppd dropping the connection and restarting, cause that would affect the timings for sure...
