libertas: Use new structure for SPI transfer delays
In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.
The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

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.
This is the essentially the same bug (and fix) that brcmfmac had, fixed

It turns out that such behavior may confuse various users of wireless

cdc_ncm: Implement the 32-bit version of NCM Transfer Block
The NCM specification defines two formats of transfer blocks: with 16-bit
fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is
implemented.
This patch adds the support of NTB-32. The motivation behind this is that
some devices such as E5785 or E5885 from the current generation of Huawei
LTE routers do not support NTB-16. The previous generations of Huawei
devices are also use NTB-32 by default.
Also this patch enables NTB-32 by default for Huawei devices.
During the 2019 ValdikSS made five attempts to contact Huawei to add the
NTB-16 support to their router firmware, but they were unsuccessful.

For sdio chip, it need the memory which is kmalloc, if it is
vmalloc from ath10k_mem_value_read, then it have a memory error.
kzalloc of ath10k_sdio_hif_diag_read32 is the correct type, so
add kzalloc in ath10k_sdio_hif_diag_read to replace the buffer
which is vmalloc from ath10k_mem_value_read.

ath10k: avoid consecutive OTP download to reduce boot time
Currently, OTP is downloaded twice in case of "pre-cal-dt"
and "pre-cal-file" to fetch the board ID and takes around
~2 sec more boot uptime.
First OTP download happens in "ath10k_core_probe_fw" and
second in ath10k_core_start. First boot does not need OTP
download in core start when valid board id acquired.
The second OTP download is required upon core stop/start.
This patch skips the OTP download when first OTP download
has acquired a valid board id. This patch also marks board
id invalid in "ath10k_core_stop", which will force the OTP
download in ath10k_core_start and fetches valid board id.

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.
