Ido Schimmel 979b9b251a mlxsw: spectrum: Clear VLAN filters during port initialization 
When a port is created, its VLAN filters are not cleared by the
firmware. This causes tagged packets to be later dropped by the ingress
STP filters, which default to DISCARD state.

The above did not matter much until commit b5ce611fd9 ("mlxsw:
spectrum: Add devlink-trap support") where we exposed the drop reason to
users.

Without this patch, the drop reason users will see is not consistent. If
a port is enslaved to a VLAN-aware bridge and a packet with an invalid
VLAN tries to ingress the bridge, it will be dropped due to ingress STP
filter. If the VLAN is later enabled and then disabled, the packet will
be dropped by the ingress VLAN filter despite the above being a
seemingly NOP operation.

Fix this by clearing all the VLAN filters during port initialization.
Adjust the test accordingly.

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.
