To support mirroring to different device types, the functions that partake in configuring the port analyzer need to be extended to admit non-trivial SPAN types. Create a structure where all details of SPAN configuration are kept, struct mlxsw_sp_span_parms. Also create struct mlxsw_sp_span_entry_ops to keep per-SPAN-type operations. Instantiate the latter once for MLXSW_REG_MPAT_SPAN_TYPE_LOCAL_ETH, and once for a suite of NOP callbacks used for invalidated SPAN entry. Put the formet as a sole member of a new array mlxsw_sp_span_entry_types, where all known SPAN types are kept. Introduce a new function, mlxsw_sp_span_entry_ops(), to look up the right ops suite given a netdevice. Change mlxsw_sp_span_mirror_add() to use both parms and ops structures. Change mlxsw_sp_span_entry_get() and mlxsw_sp_span_entry_create() to take these as arguments. Modify mlxsw_sp_span_entry_configure() and mlxsw_sp_span_entry_deconfigure() to dispatch to ops.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
