I expect the value to have the same endian-ness when printed with %llx and 
when read from sysfs.

swlab140:/home/dotanb/infiniband/newvstat/child>grep XXX vstat.c
printf("XXXXXXX %llx\n", device_attr.node_guid);

swlab140:/home/dotanb/infiniband/newvstat/child>./vstat | grep XXX
XXXXXXX 4018000002c90200

swlab140:/home/dotanb/infiniband/newvstat/child>cat
/sys/class/infiniband/mthca0/node_guid
0002:c902:0000:1840 

Why is that?

Dotan.
