Spectrum ASICs do not support matching of VLAN ID at egress. Currently, mlxsw driver forbids matching of all VLAN related fields at egress, which is too strict check. For example, the following filter is not supported by the driver: $ tc filter add dev swpX egress protocol 802.1q pref 1 handle 101 flower vlan_ethtype ipv4 src_ip .. dst_ip .. skip_sw action pass Error: mlxsw_spectrum: vlan_id key is not supported on egress. We have an error talking to the kernel The filter above does not match on VLAN ID, but is bounced anyway. Make the check more specific, forbid only matching of 'vlan_id' at egress.

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.
