[lwip-users] [lwip] dependeny of MSS on MTU

[amol patel]

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?
