gnutls_dtls_set_mtu - API function
#include <gnutls/dtls.h> void gnutls_dtls_set_mtu(gnutls_session_t session, unsigned int mtu);
gnutls_session_t session is a gnutls_session_t type. unsigned int mtu The maximum transfer unit of the transport
This function will set the maximum transfer unit of the transport that DTLS packets are sent over. Note that this should exclude the IP (or IPv6) and UDP headers. So for DTLS over IPv6 on an Ethernet device with MTU 1500, the DTLS MTU set with this function would be 1500 - 40 (IPV6 header) - 8 (UDP header) = 1452.
