RTI Connext .NET API (legacy)
Version 6.1.1

This is used in conjunction with "dds.transport.UDPv4.builtin.transport_priority_mapping_low" and "dds.transport.UDPv4.builtin.transport_priority_mapping_high" to define the mapping from the DDS transport priority (see TRANSPORT_PRIORITY) to the IPv4 TOS field. Defines a contiguous region of bits in the 32-bit transport priority value that is used to generate values for the IPv4 TOS field on an outgoing socket.
For example, the value 0x0000ff00 causes bits 9-16 (8 bits) to be used in the mapping. The value will be scaled from the mask range (0x0000 - 0xff00 in this case) to the range specified by low and high.
If the mask is set to zero, then the transport will not set IPv4 TOS for send sockets.
[default] 0.
