These warnings are wrong and were fixed a few days ago. Ppp was
warning about 54 byte (+ headers) packets with a 12 byte payload.

This is just a warning. Ppp adjusts the packet and continues
processing it.

Were there any other error messages ? It may be worth turning up
logging - maybe ``set log +debug lqm lcp''.

Not much, and statistics concerning the link quality (if you enable
lqm logging). Ppp has never done much with these stats though.
