Hi All!
In lwip stack we r using bit stuffing mechanism for escape
sequences. In the worst case if we have to bit stuff all the
characters of a packet then the size of the resulting packet will be
double of the original packet which we must be able to send using the
datalink layer. Now if the MSS * 2 > MTU we have to go for IP
fragmentation for which we have not included the code in lwip.
Is this implies that the size of the MSS should be 1/2 of the MTU to
avoid a situation like this?
Regards
Amol Patel
