Hi,
With the following patch, I met tftp errors on mx6qsabresd and mx6ul boards: " => setenv serverip 10.193.102.217; setenv ipaddr 10.193.102.31;tftp ${loadaddr} zImage Using FEC device TFTP from server 10.193.102.217; our IP address is 10.193.102.31 Filename 'zImage'. Load address: 0x12000000 Loading: * TFTP error: 'Failure to negotiate RFC1782 options' (8) Starting again "
Without the following patch, tftp work fine on mx6qsabresd and mx6ul board.

tftp: adjust settings to be suitable for 100Mbit ethernet Adjust timouts and retry counts to be suitable for loaded ethernet network. With 5 seconds timeout, 10 retries maximum, tftp is impossible even on local network with single full-speed TCP connection. 100msec timeout should be suitable for most networks tftp is used on, that is local ethernets. Timeout count really needs to be way higher, as lost packets are normal when TCP is running over the same network. Enforce 10msec minimum.
