The i40e_add_pd_table_entry() routine is being modified to handle both
cases where a backing page is passed and where backing page is allocated
in i40e_add_pd_table_entry().
For PBLE resource management, it is more efficient for it to manage its
backing pages. For VF, PBLE backing page addresses will be send to PF
driver for PBLE resource.
The i40e_remove_pd_bp() is also modified to not free pre-allocated pages and
free only ones which were allocated in i40e_add_pd_table_entry().

During close, all of the MAC filters are cleared, so the driver would be
unable to receive unicast packets after being closed and reopened.
Add the adapter's "hardware" MAC address filter in open, not init. This
ensures that the correct filter is present each time.

Due to an inverted conditional, the driver was marking all of its MAC
filters for deletion every time set_rx_mode was called. Depending upon
the timing of the calls to set_rx_mode and the processing of the admin
queue, the driver would (accidentally) end up with a varying number of
functional filters.
Correct this logic so that MAC filters are added and removed correctly.
Add a check for the driver's "hardware" MAC address so that this filter
doesn't get removed incorrectly.

MAC filters for VFs were being programmed with 0 for the VLAN value when
there was no VLAN assigned. This is incorrect and actually assigns the
VF to VLAN 0. Instead, we must use -1 to indicate that no VLAN is in
use. This change programs the filters correctly and gets rid of a bogus
error message when setting a port VLAN on an active VF.

The driver currently only maps TX and RX queues to a single MSI-X vector
per queue pair if there are exactly enough vectors for this.
Unfortunately, if we have too many vectors it will fail and allocate
queues to vectors in a suboptimal manner. Change the condition check to
allow for excess vectors. In this case, the extras just won't be used.

If the "comedi" module has been loaded with the
"comedi_num_legacy_minors" module parameter set to a non-zero value,
some reserved comedi devices get created. These can be attached to a
low-level comedi driver using the `COMEDI_DEVCONFIG` ioctl command,
which checks for the `CAP_SYS_ADMIN` capability. Of course, the comedi
device needs to be opened before the ioctl command can be sent. If the
comedi device is unattached, `comedi_open()` currently requires the
`CAP_NET_ADMIN` capability. It makes more sense to just require the
`CAP_SYS_ADMIN` capability here, so change it.
For the curious, commit a8f80e8ff9 ("Networking: use CAP_NET_ADMIN
when deciding to call request_module") changed this capability from
`CAP_SYS_MODULE` to `CAP_NET_ADMIN`, even though it doesn't seem
relevant here. The original `CAP_SYS_MODULE` capability was due to the
function having some code to request a module using a "char-major-%i-%i"
alias, but that was never compiled in and was removed by commit
f30f2c2d41 ("staging: comedi: remove check for CONFIG_KMOD").

The analog output range is not programmable, but the ranges for each of
the two analog output channels are settable via jumpers. These jumper
settings are not readable by the driver. The driver
provides a range table containing all the possible internal ranges
(+/-10V, +/-5V, 0-10V, 0-5V) to provide information to the user
application (although any range selected by the application that differs
from the jumper settings will not produce the expected voltage output).
The range table does not cover all possible ranges of the analog output
channels. The jumpers also allow an external reference voltage between
0 and 10V to be used as bipolar or unipolar output range. Add a couple
more ranges to the end of the range table to define these two external
ranges.

As used in the PCIe spec, "Downstream Port" includes both Root Ports and
Switch Downstream Ports. We sometimes checked for PCI_EXP_TYPE_DOWNSTREAM
when we should have checked for PCI_EXP_TYPE_ROOT_PORT or
PCI_EXP_TYPE_DOWNSTREAM.
For a Root Port without a slot, the effect of this was that using
pcie_capability_read_word() to read PCI_EXP_SLTSTA returned zero instead of
showing the Presence Detect State bit hardwired to one as the PCIe Spec,
r3.0, sec 7.8, requires. (This read is completed in software because
previous PCIe spec versions didn't require PCI_EXP_SLTSTA to exist at all.)
Nothing in the kernel currently depends on this (pciehp only reads
PCI_EXP_SLTSTA on ports with slots), so this is a cleanup and not a
functional change.
Add a pcie_downstream_port() helper function and use it.
