Currently, mlxsw does not differentiate between these two cases of routes with invalid nexthops: 1. Nexthops whose nexthop device is a mlxsw upper (has a RIF), but whose neighbour could not be resolved 2. Nexthops whose nexthop device is not a mlxsw upper (e.g., management interface) Up until now this did not matter and mlxsw trapped packets for both cases using the same trap ID. However, packets that should have been routed in hardware (case 1), but incurred a problem are considered exceptions and should be reported to the user. The two cases should therefore be split between two different trap IDs. Allocate a new adjacency entry during initialization and upon the insertion of the first route with an invalid mlxsw nexthop, program this entry to discard packets. Packets hitting this entry will be reported using new trap ID - "DISCARD_ROUTER3". In the future, the entry could be written during initialization, but currently firmware requires a valid RIF, which is not available at this stage.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
