OSLAM-8G Source MAC address =========================== 48bit Source address MAC address for pause control frame. NOTE: First bit of 2nd octet is as followed: This bit used to have all ports transmit the same or different source addresses in full-duplex Pause frames. 0 - All ports transmit the same Static Address (SA) 1 - Each port uses a different SA where bits 4:47 of the 'sourceMACAddress' are the same, but bits 3:0 are the port number (Port 0 = 0, Port1 = 1, Port 2 = 2, etc.)
