Could you please clarify the thinking behind this one? The P2P Interface
Address shall be unique for each group and it shall not match any
non-P2P station/AP interface address. However, a P2P Interface Address
can be same as the P2P Device Address and for many cases, it is more
resource friendly (e.g., firmware memory and RX filtering) to use the
same address when possible.
