We currently have an Rx listener function for exception traps that marks received skbs with 'offload_fwd_mark' and injects them to the kernel's Rx path. The marking is done because all these exceptions occur during L3 forwarding, after the packets were potentially flooded at L2. A subsequent patch will add support for control traps. Packets received via some of these control traps need different handling: 1. Packets might not need to be marked with 'offload_fwd_mark'. For example, if packet was trapped before L2 forwarding 2. Packets might not need to be injected to the kernel's Rx path. For example, sampled packets are reported to user space via the psample module Factor out a common Rx listener function that only reports trapped packets to devlink. Call it from mlxsw_sp_rx_no_mark_listener() and mlxsw_sp_rx_mark_listener() that will inject the packets to the kernel's Rx path, without and with the marking, respectively.

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.
