4.1.8.1. Sleep Mode

You can only put a node to sleep (set SLEEP bit in the command_config register to 1 and deassert the magic_sleep_n signal) if magic packet detection is enabled (set the MAGIC_ENA bit in the command_config register to 1).

Intel recommends that you do not put a node to sleep if you disable magic packet detection.

Network transmission is disabled when a node is put to sleep. The receiver remains enabled, but it ignores all traffic from the line except magic packets to allow a remote agent to wake up the node. In the sleep mode, only etherStatsPkts and etherStatsOctets count the traffic statistics.
