@brief This function set the transmit & receive buffer size as per the channels is used

bit 1-0 : memory size of channel #0 \n

bit 5-4 : memory size of channel #2 \n
bit 7-6 : memory size of channel #3 \n

Maximum memory size for Tx, Rx in the W5500 is 16K Bytes,\n
In the range of 16KBytes, the memory size could be allocated dynamically by each channel.\n
Be attentive to sum of memory size shouldn't exceed 8Kbytes\n
and to data transmission and receiption from non-allocated channel may cause some problems.\n
If the 16KBytes memory is already assigned to centain channel, \n
other 3 channels couldn't be used, for there's no available memory.\n
If two 4KBytes memory are assigned to two each channels, \n
other 2 channels couldn't be used, for there's no available memory.\n
