The VSI may be allocated more queues (alloc_queue_pairs) than actually
are to be used (num_queue_pairs), so only allocate rings for the queues
to be used.  The numbers will likely be the same for most VSIs, but can
be different based on how TCs are assigned and enabled.

In order to re-size queues and vectors while the interface is
still up, we need to be able to call functions to free and
re-allocate without bringing down the VSI.

We also need to reset the existing setup, update the
configuration and then rebuild again. This requires us to have
the reset flow broken down into two parts.

The hash is reported correctly in the rss field if and only if
the filter status is 3.  Other values of filter status mean
different things and we shouldn't depend on a bitwise result.

The issue was that
a & b --> returns true for b={1,2,3}
the fix is
a & b == b

Also refactor this function to use constant operations because we
are in fast path.

The current code unmaps the DMA mapping created for rx skb_buff's by
using the data_size as the the mapping size. This is wrong since the
correct size to specify should match the size used to create the mapping.

There's an issue when showing the value of packets_per_slave due to
using signed integer. The value may be < 0 and thus not put through
reciprocal_value() before showing. This patch makes it use unsigned
integer when showing it.

During suspend-resume and lancer error recovery we will cleanup and
re-initialize the resources through be_clear() and be_setup() respectively.
During re-initialisation in be_setup(), if be_get_config() fails, we'll again
call be_clear() which will cause a NULL pointer dereference as adapter->pmac_id is
already freed.
