| * If nettype is NULL, it broadcasts on all the available |
| * datagram_n transports. May potentially lead to broadacst storms |
| * and hence should be used with caution, care and courage. |
| * |
| * The current parameter xdr packet size is limited by the max tsdu |
| * size of the transport. If the max tsdu size of any transport is |
| * smaller than the parameter xdr packet, then broadcast is not |
| * sent on that transport. |
| * |
| * Also, the packet size should be less the packet size of |
| * the data link layer (for ethernet it is 1400 bytes). There is |
| * no easy way to find out the max size of the data link layer and |
| * we are assuming that the args would be smaller than that. |
| * |
| * The result size has to be smaller than the transport tsdu size. |
| * |
| * If PORTMAP has been defined, we send two packets for UDP, one for |
| * rpcbind and one for portmap. For those machines which support |
| * both rpcbind and portmap, it will cause them to reply twice, and |
| * also here it will get two responses ... inefficient and clumsy. |
