staging/mei: mei.h defining user space interface
define IOCTL_MEI_CONNECT_CLIENT and its associated structure
When the user wants to connect to a ME feature/client after
it open a file descriptor to the driver, he need to use Connect
IOCTL.
This IOCTL received a struct that contains a union of 2 other structs.
1st struct - Input Parameters:
UUID - a predefine unique that identify the ME feature, this
id per feature is constant all over the chipsets
and versions.
2nd struct Output Parameters:
MaxMessageLen - maximum message length that allowed
to be send to the feature
ProtocolVersion ME feature current protocol version.
