A small part of the first skb buffer is passed to the firmware for parsing
via DMA, while the full buffer is passed as part of the TXP.
Avoid calling DMA unmap on the first part (with a different length than map)

If rtw_core_init() fails to load the wow firmware, rtw_core_deinit()
will not get called to clean up the regular firmware.
Ensure that an error loading the wow firmware does not produce an oops
for the regular firmware by waiting on its completion to be signalled
before returning. Also release the loaded firmware.

After fixing mac80211 to allow larger A-MSDUs in some cases, there have been
reports of performance regressions and packet loss with some clients.
It appears that the issue occurs when the hardware is transmitting A-MSDUs
bigger than 8k. Limit the local VHT MPDU size capability to 7991, matching
the value used for MT7915 as well.

Two minor conflicts:
1) net/ipv4/route.c, adding a new local variable while
moving another local variable and removing it's
initial assignment.
2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
One pretty prints the port mode differently, whilst another
changes the driver to try and obtain the port mode from
the port node rather than the switch node.

The "tsid" is a user controlled u8 which comes from debugfs. Values
more than 15 are invalid because "active_tsids" is a 16 bit variable.
If the value of "tsid" is more than 31 then that leads to a shift
wrapping bug.

In commit 2d4bcbed5b ("ath11k: initialize wmi config based on hw_params") the
wmi config initialisation was moved to hw_ops->wmi_init_config() but the old
initialisation values were accidentally left to ath11k_wmi_cmd_init(). This
is very confusing, so remove the redundant values.
And this was actually so confusing that in commit aa2092a9ba ("ath11k: add
raw mode and software crypto support") I actually it caused a bug: when
ATH11K_FLAG_RAW_MODE was enabled rx_decap_mode was assigned back to
TARGET_DECAP_MODE_NATIVE_WIFI in ath11k_init_wmi_config_ipq8074(). Fix this at
the same time.

This commit marks all smd.c functions that are only used inside of smd.c as
static. Previous commits added some VHT specific setup functions non-static
which is the right thing to do in terms of having granular git commits that
compile warning free. What we really want is for local not global scope on
those functions.
This patch makes the conversion from global to local scope.

In order to send VHT parameters to wcn3680 we need to pass the extended V1
parameter structures to the firmware. These commands need to have the
version number set to 1.
This patch makes the conversion. The conversion consists of
1. Setting the version number for wcn3680 or leaving it at 0 otherwise
2. Setting the size of the packet header lower for wcn3620 and wcn3660
Once done all three chips can continue to use the same code to pass
parameters to their respective firmware. In the case of the wcn3680 the
passed structures will be slightly larger to accommodate communication of
VHT descriptors.

In order to pass 802.11ac VHT parameters from the SoC to wcn36xx we need to
use the V1 data structures associated with BSS and STA parameters.
The means of identifying a V1 data-structure is via the SMD version field.
This patch defines a INIT_HAL_MSG_V1() which operates the same way as
INIT_HAL_MSG() with the exception that it defines VERSION1 as opposed to
VERSION0.

In order to get 802.11ac working the way we want, additional parameters
need to be passed down to the firmware.
This patch takes the full remaining set of parameters defined in the
downstream riva/inc/wlan_hal_cfg.h and imports them into hal.h with some
minor name length adjustments.
This addition will allow us to pass a larger firmware configuration set
later on.
