 The PHY begins writing received bytes immediately after the {{{rx_frame_info}}}. The received SIGNAL and SERVICE fields are written to the first 5 bytes following the {{{rx_frame_info}}}. The PHY then skips 3 bytes and writes the next received byte (the first byte of the MAC header) to 8 bytes past the rx_frame_info. This convention aligns received payloads to a 64-bit boundary, easing access by the MAC software and DMAs. Generally the MAC software ignores the SIGNAL and SERVICE fields in the Rx packet buffer, instead relying on the rate/length values provided by the MAC core.
