libertas: Use new structure for SPI transfer delays

`delay_usecs` with `delay` for this driver.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure

mwifiex: set needed_headroom, not hard_header_len

hard_header_len provides limitations for things like AF_PACKET, such
that we don't allow transmitting packets smaller than this.

needed_headroom provides a suggested minimum headroom for SKBs, so that
we can trivally add our headers to the front.

The latter is the correct field to use in this case, while the former
mostly just prevents sending small AF_PACKET frames.

In any case, mwifiex already does its own bounce buffering [1] if we
don't have enough headroom, so hints (not hard limits) are all that are
needed.

====================
100GbE Intel Wired LAN Driver Updates 2020-03-10

This series contains updates to ice and iavf drivers.

Cleaned up unnecessary parenthesis, which was pointed out by Sergei
Shtylyov.

Mitch updates the iavf and ice drivers to expand the limitation on the
number of queues that the driver can support to account for the newer
800-series capabilities.

Brett cleans up the error messages for both SR-IOV and non SR-IOV use
cases.  Fixed the logic when the ice driver is removed and a bare-metal
VF is passing traffic, which was causing a transmit hang on the VF.
Updated the ice driver to display "Link detected" field via ethtool,
when the driver is in safe mode.  Updated ice driver to properly set
VLAN pruning when transmit anti-spoof is off.

Avinash fixed a corner case in DCB, when switching from IEEE to CEE
mode, the DCBX mode does not get properly updated.

Dave updates the logic when switching from software DCB to firmware DCB
to renegotiate DCBX to ensure the firmware agent has up to date
information about the DCB settings of the link partner.

Lukasz increases the PF's mailbox receive queue size to the maximum to
prevent potential bottleneck or slow down occurring from the PF's
mailbox receive queue being full.

Bruce updates the ice driver to use strscpy() instead of strlcpy().
Cleaned up variable names that were not very descriptive with names that
had more meaning.

Anirudh replaces the use of ENOTSUPP with EOPNOTSUPP in the ice driver.

Jake fixed up a function header comment to properly reflect the variable
size and use.

v2: Dropped patch 5 of the original series, where Tony added tunnel
    offload support.  Based on community feedback, the patch needed
    changes, so giving Tony additional time to work on those changes and
    not hold up the remaining changes in the series.

ice: Fix removing driver while bare-metal VFs pass traffic

Currently, if there are bare-metal VFs passing traffic and the ice
driver is removed, there is a possibility of VFs triggering a Tx timeout
right before iavf_remove(). This is causing iavf_close() to not be
called because there is a check in the beginning of iavf_remove() that
bails out early if (adapter->state < IAVF_DOWN_PENDING). This makes it
so some resources do not get cleaned up. Specifically, free_irq()
is never called for data interrupts, which results in the following line
of code to trigger:

pci_disable_msix()
free_msi_irqs()
...
BUG_ON(irq_has_action(entry->irq + i));
...

To prevent the Tx timeout from occurring on the VF during driver unload
for ice and the iavf there are a few changes that are needed.

[1] Don't disable all active VF Tx/Rx queues prior to calling
pci_disable_sriov.

[2] Call ice_free_vfs() before disabling the service task.

[3] Disable VF resets when the ice driver is being unloaded by setting
the pf->state flag __ICE_VF_RESETS_DISABLED.

Changing [1] and [2] allow each VF driver's remove flow to successfully
send VIRTCHNL requests, which includes queue disable. This prevents
unexpected Tx timeouts because the PF driver is no longer forcefully
disabling queues.

Due to [1] and [2] there is a possibility that the PF driver will get a
VFLR or reset request over VIRTCHNL from a VF during PF driver unload.
