5.3.10.1.1 Transmit Packet Command
Note: If the overall packet length is greater than 1536 bytes, the packet is silently discarded by
82598EB.
5.3.10.1.2 Request Status Command
An external BMC can initiate a request to read 82598EB manageability status by sending a Request
Status command. When received, 82598EB initiates a notification to an external BMC (when status is
ready), after which, an external BMC is able to read the status by issuing this command. The format is
as follows:

5.3.10.1.3 Receive Enable Command
The Receive Enable command is a single fragment command used to configure 82598EB. 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:
