Follow-up Comment #3, bug #36167 (project lwip):
Thanks to all for contributing to this discussion.
It is already a long time ago that we made some decissions on how to solve
this problem for our context, and we would like to share it with the
community.
For our application we needed to support jumbo frames and much larger windows,
making lwip support window scaling. We are using 32bit variables in some pcb
fields to support large windows.
We still do not know why the maximum window size is not supported, but the
correct assert in our case should be:
LWIP_ASSERT("tcp_recved: len would wrap rcv_wndn", len <= 0xffffffff -
pcb->rcv_wnd );
and we do not use windows the size of 0xffffffff.
If anybody is interested in our lwip patch to support scaling window option,
please feel free to contact me.
Thanks to everybody.
