Method Detail

mss

@Field(offset=16,
       length=16)
public int mss()

This field must only be sent in the initial connection request (i.e., in segments with the SYN control bit set). If this option is not used, any segment size is allowed.

Returns:

value of the field

mss

public void mss(int value)

Sets a new value in the field.

Parameters:
