I'm looking for a way to know if a received datagram on a raw socket has
been or not fragmented.
Reading the IP header given by the system is not interesting as the
datagram has been rassembled by the kernel. And the use of packet
socket, seems to imply to implementation in userspace of IP protocol.
Is there any system call that could give this information ? any option
to pass to getsockopt(2) ? Or any undocumented feature ?
to get my email address make one line of the two following
lines keeping chars in their respective columns
