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.
