[PATCH] Incorrect SCTP checksum calculation on 64-bit architecture

Hi,

I found that all SCTP scans were silently discarded on receiver side when
running nmap on 64-bit architecture.
The discards were due to incorrect checksum on SCTP level and might result
in a false negative.

Patch is attached.

Cheers
