1311638Srgrimes * resources amongst all associations.  The default for the UDP model is that
1321638Srgrimes * is SS_NBIO is set.  Which means all associations have a seperate send
1331638Srgrimes * limit BUT they will NOT ever BLOCK instead you will get an error back
1341638Srgrimes * EAGAIN if you try to send to much. If you want the blocking symantics you
1351638Srgrimes * set this option at the cost of sharing one socket send buffer size amongst
1361638Srgrimes * all associations. Peeled off sockets turn this option off and block. But
1371638Srgrimes * since both TCP and peeled off sockets have only one assoc per socket this
1381638Srgrimes * is fine. It probably does NOT make sense to set this on SS_NBIO on a TCP
1391638Srgrimes * model OR peeled off UDP model, but we do allow you to do so. You just use
1401638Srgrimes * the normal syscall to toggle SS_NBIO the way you want.
1411638Srgrimes *
