Time between retries of sends, in milliseconds. Defaults to 250.

The slave i2c device. If not present, the main device is used. This
lets you use two devices on the IPMB, one for master and one for slave,
in case you have a slave device that can only be a slave. The slave
will receive messages and the master will transmit.
