#define ETH_MIN_PAYLOAD   46

ETH_MIN_PAYLOAD is the minimum payload in an ethernet frame, if one sends less bytes the rest of the frame will be padded with zeros. To know when this situation happens we have added a flag in the first byte of each frame:

• 0: if there is no padding (we sent data >= the 45)
• 1-44: if there is padding (we sent data < 45)
