[patch net-next 08/15] mlxsw: spectrum: push cls_flower and cls_matchall setup_tc processing into separate functions

[Jiri Pirko]

From: Jiri Pirko <j...@mellanox.com>

Let mlxsw_sp_setup_tc be a splitter for specific setup_tc types and push
out cls_flower and cls_matchall specific codes into separate functions.
