Description Thomas Ritter 2014-04-29 15:07:09 UTC 
It seems the algorithm in dhcp_packet_checksum produced invalid checksums on BE systems (e.g. Powerpc).

I guess from other implementations the "overflow" part of the algorithm is the cause.

Yet this produces invalid UDP packets on Big endian machines.
