Date: Wed, 27 Jan 2010 23:10:04 -0700 From: "Williams, Mitch A" <mitch.a.williams@...el.com> To: "netdev@...r.kernel.org" <netdev@...r.kernel.org>, "davem@...emloft.net" <davem@...emloft.net>, Stephen Hemminger <shemminger@...tta.com> Subject: Which tool to use? Which tool to use? Just looking for a bit of direction before I go off and start coding... Our SR-IOV capable parts (like everybody else's) include simple built-in Layer 2 switch, to allow packets to be switched between the various VF devices. We need the capability of configuring this switch from userspace. There are a few features we'd like to control, like anti-spoofing, and storm control, as well as being able to completely disable the internal switch for external loopback. Mostly, however, we want to be able to add new MAC address filters to the switch. This is actually a pressing need, for SR-IOV to be really usable in a virtualized environment. In most use cases, along with VMs that are assigned VF devices, there will be a bunch of VMs talking through the PF device via a bridge. We need to add the MAC addresses of these VMs to the on-board switch, or other VMs using the VF devices won't be able to talk to them - the packets will go out on the wire instead. So, which tool do I modify to make this happen? Ethtool, or ip? I can think of convincing arguments for either, so I want to double-check with the maintainers before I dive in.
