Message-ID: <20150220035237.GH795@lunn.ch> Date: Fri, 20 Feb 2015 04:52:37 +0100 From: Andrew Lunn <andrew@...n.ch> To: roopa <roopa@...ulusnetworks.com> Cc: Guenter Roeck <linux@...ck-us.net>, Florian Fainelli <f.fainelli@...il.com>, netdev@...r.kernel.org, davem@...emloft.net, vivien.didelot@...oirfairelinux.com, jerome.oufella@...oirfairelinux.com, cphealy@...il.com Subject: Re: [PATCH RFC 2/2] net: dsa: bcm_sf2: implement HW bridging operations > - we keep the SW bridge fdb in sync with the HW fdb, which leads to: I don't think this is going to be easy or efficient. At least for the 88e6060 there is no interrupt when there is a change to the database. So we are going to have to poll. And the only way to figure out if anything has changed is to read it all out and compare against the last read. I suppose we only need to update the SW fdb shortly after the SW bridge had to perform a flood because it had no entry for the destination MAC, or after an entry sync'ed into the SW fdb reaches timeout age.
