    _______________________________________________________

Details:

If length specified into IP header is to big at input, pbuf_realloc crashes.
To prevent this, I propose to add a check before pbuf_realloc : length
specified into IP header should be less or equal than pbuf tot_len. Else
packet is rejected.

Regards
Marc
