Request flags

In a request, the "flags" field specifies the actions to be performed by the LRI1K and

whether corresponding fields are present or not.

The flags field consists of eight bits.

The bit 3 (Inventory_flag) of the request flag defines the contents of the 4 MSBs (bits 5 to 8).

When bit 3 is reset (0), bits 5 to 8 define the LRI1K selection criteria.

When bit 3 is set (1), bits 5 to 8 define the LRI1K Inventory parameters.
