Meaning of each bit in AVP header:

P bit: The P bit indicates the need for encryption for end-to-end security.

M bit: Mandatory bit, indicates whether support of the AVP is required.

V bit: Vendor-Specific bit, indicates whether the optional Vendor-ID field is present in the AVP header.

When set the AVP Code belongs to the specific vendor code address space.

The M bit MUST be set. The V bit MUST NOT be set.
