Call the netif_set_real* functions in order to make sure
the stack knows about how many queues we have, in order
for RFS/RPS/XFS to work correctly.

When the ethtool testing starts it sets the I40E_TESTING state
bit, which blocks new netdev opens so that things don't get
confused, while the testing might be messing with register and
other things. Unfortunately, that was keeping the PF resets
after the register test from working correctly because the netdev
would not get reopened. This patch reorders the tests to put the
register test last as it is the only one that needs a reset, and
we wait to trigger the reset until after we clear the
I40E_TESTING bit.

I40E_ITR_NONE was being used as an ITRN register index by
accident because it was easily associated with the I40E_RX_ITR
and friends defines.
Change the name slightly in order to make it clear that
I40E_ITR_NONE is really associated with the DYN_CTL register
sets.

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.

driver to request the hardware to filter on L2 parameters.
This is an implementation of the driver access to a new firmware

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.
