Follow-up Comment #4, bug #54253 (project lwip):

>Anyway, the real way to fix that is to provide entropy from your TRNG using
LWIP_RAND macro.

Probably yes, but GSM modem startup time is random enough to get unique magic
number. Anyway after ppp exchange start magic_randomize() called from
ppp_input() at random moments, so using TRNG to get one random number seems
overkill to me.
