TCP receive mail box is a per socket mail box, when the application receives packets

from TCP socket, LWIP core firstly posts the packets to TCP receive mail box and the

application then fetches the packets from mail box. It means LWIP can caches maximum

for all TCP sockets is TCP_RECCVMBOX_SIZE multiples the maximum TCP socket number. In other
|

|
words, the bigger TCP_RECVMBOX_SIZE means more memory.
|

|
On the other hand, if the receiv mail box is too small, the mail box may be full. If the

mail box is full, the LWIP drops the packets. So generally we need to make sure the TCP

On the other hand, if the receiv mail box is too small, the mail box may be full. If the
