Message-Id: <20170526063740.8909-18-jiri@resnulli.us> Date: Fri, 26 May 2017 08:37:39 +0200 From: Jiri Pirko <jiri@...nulli.us> To: netdev@...r.kernel.org Cc: davem@...emloft.net, idosch@...lanox.com, mlxsw@...lanox.com, stephen@...workplumber.org, nikolay@...ulusnetworks.com Subject: [patch net-next 17/18] mlxsw: spectrum: Implement common FID core From: Ido Schimmel <idosch@...lanox.com> The device supports three types of FIDs. 802.1Q and 802.1D FIDs for VLAN-aware and VLAN-unaware bridges (respectively) and rFIDs to transport packets to the router block. The different users (e.g., bridge, router, ACLs) of the FIDs infrastructure need not know about the internal FIDs implementation and can therefore interact with it using a restricted set of exported functions. By encapsulating the entire FID logic and hiding it from the rest of the driver we get a code base that it much simpler and easier to work with and extend. For example, in the current Spectrum ASIC only 802.1D FIDs can be assigned a VNI, but future ASICs will also support 802.1Q FIDs. With this patch in place, support for future ASICs can be easily added by implementing a new FID operations according to their capabilities.
