BSP_DEFAULT_ENET_OUI: accept() never return when MAC address is changed

By default, the MAC adress OUI is defined with:

#define BSP_DEFAULT_ENET_OUI                { 0x00, 0x00, 0x5E, 0, 0, 0 }


then when I'm using ENET_get_mac_address, the 3 MSB Bytes are 0x00, 0x00, 0x5E, and the 3 LSB bytes are according transmitted parameter value.

So, when device is initialized with MAC address 00.00.5E.1.30.39, all work correctly.

Then, I only modify the OS code to test:

#define BSP_DEFAULT_ENET_OUI                { 0x53, 0x45, 0x52, 0, 0, 0 }


So device is initialized with the following MAC address:


Then in this case, when I call accept:

DV_Eth_TCPClientSocketID = accept(DV_Eth_TCPSocketID, &DV_Eth_TCPClientSocketAddr, &DV_Eth_TCPClientSocketAddrLen);


MQX wait a socket connexion, but even if I connect my computer software to connect on the socket, accept function never return.


I not test with other MAC address, but why this work with "pre defined MAC OUI" but not with a "specific MAC OUI"?
