#define TCP_MAX_SEG_SIZE_RX (536u)
Description
TCP Maximum Segment Size for RX. This value is advirtised during connection establishment and the remote node should obey it. This should be set to 536 to avoid IP layer fragmentation from causing packet loss. However, raising its value can enhance performance at the (small) risk of introducing incompatibility with certain special remote nodes (ex: ones connected via a slow dial up modem).
