Jiri Pirko says: ==================== mlxsw: Identical routes handling Ido says: The kernel can store several FIB aliases that share the same prefix and length. These aliases can differ in other parameters such as TOS and metric, which are taken into account during lookup. Offloading devices might not have the same flexibility, allowing only a single route with the same prefix and length to be reflected. mlxsw is one such device. This patchset aims to correctly handle this situation in the mlxsw driver. The first four patches introduce small changes in the IPv4 FIB code, so that listeners of the FIB notification chain will be able to correctly handle identical routes. The last three patches build on top of previous work and introduce the necessary changes in the mlxsw driver. The biggest change is the introduction of a FIB node, where identical routes are chained, instead of a primitive reference counting. This is explained in detail in the fifth patch. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
