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

[shilei yu]

Follow-up Comment #9, bug #50914 (project lwip):

TCP_CHECKSUM_ON_COPY_SANITY_CHECK seems not work if i set
LWIP_CHECKSUM_ON_COPY==0(TCP_CHECKSUM_ON_COPY will be 0 too),
So i should set LWIP_CHECKSUM_ON_COPY==0 or LWIP_CHECKSUM_ON_COPY==1 and
TCP_CHECKSUM_ON_COPY_SANITY_CHECK == 1 to check whether the checksum is error,
right?

Thanks for your response! it is very helpful.
