mlxsw: core: Prevent trap group setting if driver does not support EMAD
Vadim Pasternak authored
Avoid trap group setting if driver is not capable of EMAD support.
For example, "mlxsw_minimal" driver works over I2C bus, overs which
EMADs cannot be sent.
Validation is performed by testing feature 'MLXSW_BUS_F_TXRX'.

Fixes: 74e0494d

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.
