[lwip-users] 2 packets received in tcp and passed as only 1 with doubled size

[gussabina]

Hello:

I'm using lwIP 1.4.1 with FreeRTOS 7.30 running on Atmel ATSAM4E, with an
application creating a tcp (mqtt) connection to the cloud via ethernet. I
noticed in some cases, where 2 consecutive packets are sent from the cloud
(in a very short time between them), even when 2 TCP segments are received
in the ethernet interface (as observed in wireshark), the stack passes only
one packet with double size....
In this case the application fails as it's not what would expect....

How can this be avoided?

Thanks
Gus
