Petr Machata a76ca8afd4 mlxsw: Set port STP state on bridge enslavement
When the first port joins a LAG that already has a bridge upper, an
instance of struct mlxsw_sp_bridge_port is created for the LAG to keep
track of it as a bridge port. The bridge_port's STP state is initialized to
BR_STATE_DISABLED. This made sense previously, because mlxsw would only
ever allow a port to join a LAG if the LAG had no uppers. Thus if a
bridge_port was instantiated, it must have been because the LAG as such is
joining a bridge, and the STP state is correspondingly disabled.

However as of commit 2c5ffe8d72 ("mlxsw: spectrum: Permit enslavement to
netdevices with uppers"), mlxsw allows a port to join a LAG that is already
a member of a bridge. The STP state may be different than disabled in that
case. Initialize it properly by querying the actual state.

This bug may cause an issue as traffic on ports attached to a bridged LAG
gets dropped on ingress with discard_ingress_general counter bumped.

README

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.
