Subject: snmp: use a 16-bit checksum, not a 15-bit one.
X-Git-Tag: 0.5.5~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1066729b4f27ed979d871770a3f3a41c61a5ee2b;p=thirdparty%2Flldpd.git

snmp: use a 16-bit checksum, not a 15-bit one.

We could use a 31-bit checksum but we would have to write it. We
prefer to minimize the code.
