• Get System MAC Address - This command allows the MC to retrieve the system MAC address
used by the NC. This MAC address can be used for a shared MAC address mode.
• Keep Phy Link Up (Veto bit) Enable/Disable - This feature enables the BMC to block Phy reset,
which might cause session loss.
• TCO Reset - Allows the MC to reset 82598EB.
• Checksum offloading - Offloads IP/UDP/TCP checksum checking from the MC.
These commands are designed to be compliant with their corresponding SMBus commands (if existing).
All of the commands are based on a single DMTF defined NC-SI command, known as OEM Command.
This command is as follows.
5.4.2.2.1.1 OEM Command (0x50)
The OEM command can be used by the MC to request the sideband interface to provide vendor-specific
information. The Vendor Enterprise Number (VEN) is the unique MIB/SNMP private enterprise number
assigned by IANA per organization. Vendors are free to define their own internal data structures in the
vendor data fields.

5.4.2.2.1.2 OEM Response (0xD0)
Below is the vendor specific format for commands, as defined by NC-SI.
