[U-Boot] http client?

[jeffery palmer]

I didn't add fragmenting but without further investigation into it I would
assume that the fragmented packets were discarded. The tftp program still
acted like it was downloading at a larger block size but I doubt it actually
was.

I have noticed a reasonable amount of lost packets as well which is odd. We
have a 100 meg fiber to our servers and I still get lost UDP packets. I
think there is a pending bug in the network layer regarding this.

I will have a look at the patch and revert. Thanks.

I'm sorry, I misread that in your message.

laziness, mainly. And personal preference over simpler code where possible.

But you are right, no real reason. So I've done it trivially (see patch
posted today).  On my LAN it doesn't make any noticeable
difference: only I have more lost packets if I increase the block size too
much, so it gets worse.

I would like to know if it helps Jeffery Palmer.

BTW: you (Jeffery) told you tried a blocksize of 16k, but how could it work
if u-boot refuses fragments? Did you add defragmenting to the code first?
