20 kB is quite a lot, I added a little bit overhead in PPP (especially 
for PPPoS) when I added the separation layer between PPPo(S|E|L2TP) but 
20 kB sound like too much because I also removed some useless features 
in the meanwhile (ARP is disabled, WINS is disabled, DNS is optional, 
AUTH is optional, …).

I checked to be sure, reverted up:

lwip         604a92d
lwip-contrib b2cf204 

Size are in byte, on x86_64, binaries not stripped:


466440   no ppp
857560   PPP (full featured except PPP_SERVER)

PPP size: 391120


Git HEAD

480456   no ppp
856040   PPP (full featured except PPP_SERVER)

PPP size: 375584


Not me ;-)
