To enable avail_thresh_triggered on port 1 and disable current host

To disable avail_thresh_triggered and current host shaper on port 1:

Outer VLAN processing is supported after firmware v8.4, kernel driver
also change the default behavior to support this feature. To align with
kernel driver, add support for outer VLAN processing in DPDK.
But it is forbidden for firmware to change the Inner/Outer VLAN
configuration while there are MAC/VLAN filters in the switch table.
Therefore, we need to clear the MAC table before setting config,
and then restore the MAC table after setting.
This will not impact on an old firmware.

The header file "roc_io.h" uses the "__plt_always_inline" macro but
don't include "roc_platform.h" to get the definition of it. This
inclusion is not necessary for compilation, but the lack of it can
confuse some indexers - such as those in eclipse, which reports the
lines:
"static __plt_always_inline uint64_t"
as possible definitions of a variable called "uint64_t". This confusion
leads to uint64_t being flagged as an unknown type in all other parts of
the project being indexed, e.g. across all of DPDK code.
Adding in the include of roc_platform.h makes it clear to the indexer
that those lines are part of a function definition, and that allows
eclipse to correctly recognise uint64_t as a type from stdint.h
