/* This constant (SCTP_MAX_READBUFFER) define
 * how big the read/write buffer is
 * when we enter the fd event notification
 * the buffer is put on the stack, so the bigger
 * it is the more stack you chew up, however it
 * has got to be big enough to handle the bigest
 * message this O/S will send you. In solaris
 * with sockets (not TLI) we end up at a value
 * of 64k. In TLI we could do partial reads to
 * get it all in with less hassel.. but we
 * write to sockets for generality.
