 * number of offload peer must be n+1 of which n buffers will be used for
 * self peer and the remaining 1 is used for offload peer to support chatter
 * mode for single STA.

 * Technically the macro should be 1 however the current firmware requires n+1.

 * to allocate buffers for self peer and offload peer independently.
