[lwip-devel] [bug #50914] TCP server don't update the ack num

[shilei yu]

Follow-up Comment #4, bug #50914 (project lwip):

@goldsimon
Thanks for your response.
My PC(TCP server) is windows7 and device(TCP client) runs mbed OS which use
lwip as TCP/IP stack.
I have confirmed lwip version is 2.0.0 in init.h.
I Use TCPUDPDbg as TCP server on PC, but i don't think it was related the
issue, it is just application software, the ack num depends on windows TCP/IP
stack.
i don't understand about the checksum, do you mean the PC receive the packet
but the checksum is wrong, so drop it?
