Hi,
just to remind all: This issue is only happening when there is a TCP
fragmentation in place!
I'm using the Netconn interface. If I push these amount of data with MSS set to
1500, the issue does not happen. The packets are queued into LwIP's memory
unless there is not enough space to store the next packet, NETCONN_WRITE
returns correctly an ERR_WOULDBLOCK and I'll try again after a few
milliseconds. That's working without issues.
Once the MSS < packet size the issue kicks in as soon as I'm giving more than
one packet into LwIP, even without filling up LwIP's memory and pbuf's.
There might be some workarounds, but the preferred solution would be to find
the issue in LwIP here. I don't think it's in the PPP, so maybe it's something
which is also left in LwIP 2.0 …
