Since nearly everything we do is synchronous, using the interrupt-on-error bit
is unnecessary and causing unneeded interrupts. If anyone wants to use the bit
they can turn it on in individual AQ requests using the cmd_details parameter.

Call AQ to release any reservation held by this PF on the NVM resource
lock on startup, in order to clear anything that might have been left over from
a previous run. The lock is only cleared by the requestor calling for it to be
cleared, on power-on, or firmware reset. This should help limit the need for
rebooting a customer machine if something goes wrong on a firmware update or

When communicating with VF devices over the AQ, the FW refers to the
VF by its global VF ID, not local the VF ID with reference to its
parent PF. Since the global and local VF IDs are identical for PF 0,
the code worked correctly on PF 0.
However, we cannot just use global IDs throughout the code as most of
the other references to the VF (VSI setup, register offsets, etc.)
require the local VF ID. Instead, we just add or subtract our base VF
ID when sending and receiving AQ messages.

Enabling the default port on the VEB causes all outgoing traffic from
virtual functions to be copied to the physical function. The default
port is only supposed to be used if you wish to bridge the physical
function to a SW switch such as Open vSwitch or the Linux bridge. That
allows the SW switch to route traffic to VMs that are not using a
virtual function.
Eventually we'll want to implement the ndo_fdb_add, ndo_fdb_del, and
ndo_fdb_dump functions. The ndo_fdb_add function would set the
default port on the VEB in those cases where the MAC/VLAN address
filters have overflowed. Normally we would not want to use it.

The allocation and clearing of rings for a VSI should be
using the alloc_queue_pairs and not num_queue_pairs.
The alloc_queue_pairs per VSI is a pre-allocated number
of queues assigned to a VSI; based on number of TCs enabled
only certain number of queues may be used from that. This
is mainly valid only for the LAN VSI case as that is the
only VSI that may be enabled with multiple traffic classes.
In the future the number of TCs may change based on DCBX
configuration.
The actual number of queues that are enabled/configured is
based on the number of TCs enabled for a given VSI and that
is stored in num_queue_pairs.
With this change num_[tr]x_queues is unused so remove them.

When cleaning the ARQ, we must reinitialize the buffer size each time we

length in the same field. Without this change, subsequent messages can
be truncated to the length of the previous message.

Introduce i40e_irq_dynamic_disable_icr0 and use it and its previously-
