Follow-up Comment #5, bug #56397 (project lwip):

Hi Simon,

Just got one of our customer got this bug with our new version with more logs.
But, because of a typo in added log, I don't get the value for the rcv_wnd.
:-/

The only value I got is TCP_TCPLEN(cseg) which is 1460.

Default rcv_wnd is 17520 (12*MSS) at session start. This is during a HTTPS
download (using an ALTCP_TLS socket) where records can be up to 16384 bytes
(+5 +24).

I'll come back here when I'll get rcv_wnd value...
