[U-Boot-Users] ARP request packet size

Hello all, I am porting u-boot and i am writing network driver.When uboot tries to send Arp request the packet size is 42 bytes and hence the other machines in network dont accept the request as the minimum size of ethernet frame should be 64bytes and hence ARP request packet is dropped. The problem is should the padding of packet to 64bytes should be done in driver code or there is other solution ???? Regards, Pradeep.
