transmission part on TCP Server mode if the detail is needed.
But this value itself is not the physical address to write. So, the physical address should be
Now, write the transmission data to dst_ptr as large as the user wants. (* There may be a
After that, be sure to increase the Sn_TX_WR value by the size of writing data. Finally, give
