132  * is SS_NBIO is set.  Which means all associations have a seperate send
133  * limit BUT they will NOT ever BLOCK instead you will get an error back
134  * EAGAIN if you try to send to much. If you want the blocking symantics you
135  * set this option at the cost of sharing one socket send buffer size amongst
136  * all associations. Peeled off sockets turn this option off and block. But
137  * since both TCP and peeled off sockets have only one assoc per socket this
138  * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
139  * model OR peeled off UDP model, but we do allow you to do so. You just use
140  * the normal syscall to toggle SS_NBIO the way you want.
