[U-Boot] TFTP Timeout Interval problem

[Gong Q.Y.]

Hi,

I got a problem with tftp and found this patch.
-------------
commit 620776d734e4b126c407f636bda825a594a17723

    tftp: adjust settings to be suitable for 100Mbit ethernet
--------------
The default timeout is changed to 100 (ms) and this causes "TFTP error: 'Unsupported option(s) requested' (8)".

Because the option is equal to timeout/1000, now it's zero(100/1000 -> 0) which is not supported.
Actually I find in an original doc RFC-2349 which specifies this value should range between "1" and "255" seconds.

So I think there may be a conflict?
Look forward to your help.

This is my test log:
