Subject: [PATCH 1/2] net: ethtool: add support for reset of AP inside NIC interface.
Date: Thu, 30 Nov 2017 11:35:59 -0800 [thread overview]
Message-ID: <1512070560-16739-2-git-send-email-scott.branden@broadcom.com> (raw)
In-Reply-To: <1512070560-16739-1-git-send-email-scott.branden@broadcom.com>
Add ETH_RESET_AP to reset the application processor(s) inside the NIC
interface.
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.
