Details:

file: src\core\snmp\mib_structs.c

If MIB array size grows over 255, some index variables used in 
snmp_expand_tree() get an overflow.

I changed 3 'u8_t j' to u16_t and now it works fine
lines in GIT head:
740, 784, 983

because i'm using a rather old lwip code base, i didn't try to post a diff.

Greetings
