Sn_TXMEM_SIZE
It configures the internal TX Memory size of each SOCKET. TX Memory size of each SOCKET is
Ex1) SOCKET 0 : 8KB, SOCKET 1 : 2KB
Ex2) SOCKET 2 : 1KB, SOCKET 3 : 1KB
Ex3) SOCKET 4 : 1KB, SOCKET 5 : 1KB
Ex4) SOCKET 6 : 1KB, SOCKET 7 : 1KB
As shown above ex1) ~ ex4), total size of each SOCKET’s RX memory (Sn_RXMEM_S
