So i found this manual here: http://www.silica.com/fileadmin/02_Products/Productdetails/Texas_Instruments/SILICA_TI_66AK2E05-ds.pdf Glad there is an open document! There are a couple of ethernet switch chips I can spot there. Can i control those with "bridge" or say "brctl" utilities? I can see the bridge ports are exposed and i should be able to control them via ifconfig or ip link. Thats what "standard kernel infrastructure" means. Magic hidden in a driver is not. Take a look at recent netconf discussion (as well as earlier referenced discussions): http://vger.kernel.org/netconf-nf-offload.pdf Maybe we can help providing you some direction? The problem is it doesnt seem that the offload specs for those other pieces are open? e.g how do i add an entry to the L2 switch? cheers, jamal From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jamal Hadi Salim Subject: Re: [PATCH v2 0/3] net: Add Keystone NetCP ethernet driver support Date: Tue, 09 Sep 2014 07:44:09 -0400 Message-ID: <540EE809.9020901@mojatatu.com> References: <1408115562-22487-1-git-send-email-santosh.shilimkar@ti.com> <20140821.163612.282672926741753926.davem@davemloft.net> <53F79DC5.8030003@ti.com> <540DC00F.1080103@ti.com> Mime-Version: 1.0 Content-Type: text/plain; charset=windows-1252; format=flowed Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <540DC00F.1080103-l0cyMroinI0@public.gmane.org> Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Santosh Shilimkar , David Miller Cc: netdev-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org, linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, robh+dt-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org, grant.likely-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org, devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, sandeep_n-l0cyMroinI0@public.gmane.org, Benjamin LaHaise , shrijeet Mukherjee List-Id: devicetree@vger.kernel.org On 09/08/14 10:41, Santosh Shilimkar wrote: >> The NetCP plugin module infrastructure use all the standard kernel >> infrastructure and its very tiny.
