Sergio,
Thanks for the info.
This 'buggy driver' you talk about, is this with lwIP 1.4.0 and is there a
way to fix it? Or a link to other solutions to the problem.
Thanks,

Hiļ¼Thanks for your reply, I am running the TI TM4C without a system. I am
very new to TCP/IP, what I am trying to achieve is send a file on the
computer side, and pass the file to the TI board which can receive it and
save it on the SD card, this is a project, we are trying to realize this

You have some TI stuff with lwIP, with some web server using some lwIP
API you don't mention and you have an OS or you don't, but that works
OK, if I'm clever enough to decipher that from your description.
Then you have a RBPI, that already has a TCP/IP stack with Berkeley
sockets, so there is

Yes indeed!
Vendor drivers are (sometimes) just demos, and we've seen this a couple
(many) times.

Your "TCP packets larger than one Ethernet packet" translate to two
Ethernet frames.
Sometimes, in the capture file, you see that the first one is
acknowledged and some time(out) after the second one is retransmitted.
Assuming the echorequester is a PC and the echoresponder is an lwIP
device, th

So, git bisect all the way back to the Oct 9 commit didn't show anything.
Poking around looking at some of the contents of the netif structure

Your device seems to be missing frames.

Hello,
I have switched the network code I was using to the 2.0.0-beta1 release that
we were notified about earlier in the week and my previously working
application code is now throwing an error.
The initialisation of the stack is as follows:
netif_add(&lwipnetif, &ipaddr, &netmask, &gat
