10.5.9.1.8 Clear all Filters Command
The Clear all Filters command is a single fragment command capable of clearing all the receive filters
currently programmed for manageability traffic.
10.5.9.2 Read SMBus Transactions
This section details the pass-through read transactions that the MC can send to the I210 over SMBus.
SMBus read transactions lists the different SMBus read transactions supported by the I210. All the read
transactions are compatible with SMBus read block protocol format.
0xC0 or 0xD0 commands are used for more than one payload. If MC issues these read commands, and
the I210 has no pending data to transfer, it always returns as default opcode 0xDD with the I210 status
and does not NACK the transaction.
If an I2C quick read command is received, it is handled as a I210 Read Status command (See
Section 10.5.9.2.2 for details).
If a read command is received while the internal firmware is not ready, the following answer is
provided:
