2. PM/Myrinet for Myrinet 2000 with serial and fiber links (M3S-PCI64B and M3F-PCI64B)
   PM/Myrinet for Myrinet 2000 gets more stable. However Zero-copy message transfer is not stable yet. Myrinet 2000 with SAN link should be worked using myrinet network type and, can be used with both myrinet and myrinet2k network types.
   

   CAUTION: Myinet 2000 NICs with serial link, which delivered before the middle of April 2001, may cause severe CRC errors such as hundreds of CRC errors in one hour. So network stress test using rcstest should be processed, and checked using following command.
   # cat /proc/pm/myrinet/0/info
