Re: [lwip-users] LLDP Implementation for lwIP

Hi Amit,

of course you must make up for a licence before sharing anything. 
Personally, I'm not sure I would contribute to anything not compatible to 
the lwip licence though.

Hello Simon

The lwIP license would not be touched. The only change will be that the
lldp.c and lldp.h files may have copyright information w.r.t the
organization I work for (*and I am clarifying with the legal team).

lwIP's license is available nearly everywhere (website, sources, etc.).

What I don't get is: where would the lwIP license be touched if you write
an LLDP stack?

[lwip-users] tcp_echo sample for lpc17xx (LPCopen 2.10)

[TJO]

Hi all, 

I'm currently trying out some lwip demo's for my LPC1788 hardware.
In the LPCopen 2.10 package there is some demo application (tcp echo) using
lwip 1.4.1

One using raw TCP/IP standaolone (No RTOS) and one using Netconn API in
FreeRTOS.
I have written a simple TCP client test app in c#. It connects to the IP
number, sends a package in 128 byte  chunks. The lwip demo returnes every
received bytes.
The test application measure the roundtrip time (Write to read). 
I'm using 500 bytes data for test.

The lwip RAW TCP demo runs fine. Ok performance and round trip times
Now the same test on the lwip Netconn FreeRTOS demo har poor performance.
Some roundtrip time takes about ~300 ms. (Nagle is disabled in the lwip demo
and in the test application). When I reduce the returned data, from the TCP
echo demo, to be fixed at 10 bytes no roundtrip of 300 ms occure.
Seems the netconn_write can take it times if the stack is busy?
Also, after a while the lwip asserts with ".../..." ??


My question. Is it the lwip Netconn FreeRTOs demo poorly made?
Is it the netconn API that has problem?

Any experience with freeRtos, lwip and netconn?

thanks, Thomas

Hello Simon

OK, I will set it up on git. I wanted to however check before I do that is
that is there a contributor license agreement/contributors agreement for
lwIP that I need to be aware of?

Did you check the RTOS SDK? It seems the lwIP version included there
is much more recent (although quite old, they're still using ipX_addr_t)
and not as heavily modified.

Right. Now that I found the sources they provide, I'm not sure what you're 
trying to do
is a good idea, unless you have plenty of time :-)

On the other hand, you could properly fix their port to use "vanilla" lwIP plus 
the
appropriate porting mechanisms and send it back to them? ;-)

BTW: I didn't quite get if all those attributes to functions/variables are 
really required
or if it's just a kind of optimization that is rather optional...

That's not an lwIP structure: I've never heard of that name.


Oh, the vendor had put that into ip_addr.h
Heavily modified... even more than I thought.

What about setting up a repository somewhere 8e.g. github?) and posting a link 
here?

As i said at the beginning, I'd be interested to see an lldp implementation.
However, lwIP is an *IP* stack, so I'm not (yet?) convinced the lwIP git 
repository
is the right place for it.

That being said, I didn't get your descriptions about the code, so putting it 
somewhere
for review might really be the best idea to proceed.
