@deftypefun {void} {gnutls_dtls_set_mtu} (gnutls_session_t @var{session}, unsigned int @var{mtu})

@var{session}: is a @code{gnutls_session_t}  type.

@var{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.
