IPC@CHIP Documentation - SC12 @CHIP-RTOS V1.10

new socket is opened and bound to the same port as the earlier socket.
Developer Notes
Since @CHIP-RTOS version 071, the API_OPENSOCKET call sets the SO_REUSEADDR option to '1' as default for
all TCP sockets. So calling this API is no longer necessary.

The 8 bits in the IP datagram Type-Of-Service field are defined as follows:
Bits 0: unused bit (must be 0)
Bits 1-4: Type of Service, see TCP/IP documentation e.g.
Section 3.2 of "TCP/IP Illustrated, Volume 1" by W. Richard Stevens.
At most one of these four bits is set.
Bits 5-7: "Precedence field" (unused today)
Note: Many routers ignore this IP datagram header field.
