Current ETH_RESET_MGMT supports a management processor inside this NIC. This is typically used for remote NIC management purposes. Application processors exist inside some SmartNICs to run various applications inside the NIC processor - be it a simple algorithm without an OS to as complex as hosting multiple VMs. Signed-off-by: Scott Branden Reviewed-by: Andrew Lunn --- include/uapi/linux/ethtool.h | 1 + 1 file changed, 1 insertion(+) diff --git a/include/uapi/linux/ethtool.h b/include/uapi/linux/ethtool.h index ac71559..44a0b67 100644 --- a/include/uapi/linux/ethtool.h +++ b/include/uapi/linux/ethtool.h @@ -1686,6 +1686,7 @@ enum ethtool_reset_flags { ETH_RESET_PHY = 1 << 6, /* Transceiver/PHY */ ETH_RESET_RAM = 1 << 7, /* RAM shared between * multiple components */ + ETH_RESET_AP = 1 << 8, /* Application processor */ ETH_RESET_DEDICATED = 0x0000ffff, /* All components dedicated to * this interface */ -- 2.5.0
