This patch adds the initializzation code to disable the hardware
vlan support for VLAN Tag stripping by default for now.
Proper support of "hardware VLAN assitance" feature would
soon come in the next coming patches.

Why not call it directly?
Hi Sergei,
The wrapper API abstraction has been put intentionally. The reason is
the same code
is suppose to run across different SoCs so it is always clean approach
to hide it so
that even if there are differences in the way we access or configure
hardware
in other SoCs basic interface of the SET API remains same!!
Therefore, we are in favour of keeping the above wrapper and therefore not
changing now.
Best regards
Salil

Thanks for this. I have changed this in PATCH V7 already floated.
