NetServerEther was not being cleared in the tftp server code, so the destination MAC address would be whatever the last destination MAC address was.

Scenario: U-Boot: dhcp tftpsrv Host: Send device WRQ Device: Responds with ACK to dhcp server mac address with host ip address

By clearing NetServerEther, we force a lookup of the host MAC address to go with the associated host IP.
