[U-Boot] eth_send, eth_rx

Hi Team,

I want to implement eth client like application in the form of some command. I am going through the TFTP protocol implementation so that I can understand the flow.

I want to make sure about following..

After sending packet using eth_send or NetSendUdpPacket, eth_rx function is polled inside NetLoop and on reception of packet NetReceive function will be called by eth_rx. eth_rx function must be called continuously i.e. polling. Is this correct understanding? is polling eth_rx the only solution?
