TCO Reset
This command causes the NC to perform TCO reset, if force TCO reset is enabled in the
NVM.
If the MC has detected that the operating system is hung and has blocked the Rx/Tx
path, the force TCO reset clears the data-path (Rx/Tx) of the NC to enable the MC to
transmit/receive packets through the NC.
When this command is issued to a channel in a package, it applies only to the specific
channel.
After successfully performing the command, the NC considers the Force TCO command
as an indication that the operating system is hung and clears the DRV_LOAD flag
(disable the LAN device driver).
