I've tested Ethernet speed on i.MX6 Sabre-SD board and found a strange problem.
When I download a file using ftpget command from a FTP server on Ubuntu PC(vsftpd), the transfer speed is good(over 30Mbps).
But from a FTP server on Windows PC(Cerberus FTP server) within the same network, the transfer speed is very poor(about 3Mbps).
LTIB version 12.09 S/W platform and 100baseTx-FD network.
I wonder what caused this difference.
