The VNIC driver needs multiple parameters (IOCGUID, DGID etc) from user space
to connect to the EVIC. For this the "name=value" mechanism is used for
a write-only sysfs file as an input method to the driver.
The driver follows the one value per file sysfs rule when it returns any data
with each readable file returning only a single value.
