System Manageability—Ethernet Controller I210

10.5.9.1.1 Transmit Packet Command
The Transmit Packet command behavior is detailed in Section 10.5.7. The Transmit Packet fragments
have the following format.
The payload length is limited to the maximum payload length set in the Flash. If the overall packet
length is bigger than 1536 bytes, the packet is silently discarded.
10.5.9.1.2 Request Status Command
An external MC can initiate a request to read the I210 manageability status by sending a Request
Status command. When received, the I210 initiates a notification to an external MC when status is
ready. After this, the external controller will be able to read the status, by issuing a read status
command (see Section 10.5.9.2.2).
The format is as follows:
10.5.9.1.3 Receive Enable Command
The Receive Enable command is a single fragment command used to configure the I210. This command
has two formats: short, 1-byte legacy format (providing backward compatibility with previous
components) and long, 14-byte advanced format (allowing greater configuration capabilities). The
Receive Enable command format is as follows:
