For QCA6390, bss peer must be created before vdev is to start. This
change is to start vdev if a bss peer is created. Otherwise, ath11k
delays to start vdev.
This fixes an issue in a case where HT/VHT/HE settings change between
authentication and association, e.g., due to the user space request
to disable HT.

Currently 256 bitmap in blockack frames is being set only for AP mode.
Fix this to set whenever beacon has changed and has HE capability, there
by supporting mesh as well.

HE operation IE in beacons is constructed based on userspace params,
which firmware might not be aware of. This causes firmware not to
configure TXOP duration based RTS threshold which could cause mismatch
in behaviour with respect to what is being advertised in beacons. This
patch sends HE operation IE fetched from beacon to firmware using
WMI interface for configuration.

It was observed that the codepath for the ATH11K_SKB_HW_80211_ENCAP was
used even when the IEEE80211_TX_CTRL_HW_80211_ENCAP was not enabled for a
an skbuff. This became even more prominent when the QCAs wlan-open patchset
for ath11k [1] was applied and a sane looking fix just caused crashes when
injecting frames via a monitor interface (for example with ratechecker):

Problem is that the state of ath11k_skb_cb->flags must be considered
unknown and could contain anything when it is not manually initialized. So
it could also contain ATH11K_SKB_HW_80211_ENCAP. And this can result in the
code to assume that the ath11k_skb_cb->vif is set - even when this is not
always the case for non ATH11K_SKB_HW_80211_ENCAP transmissions.

The driver_data area of ieee80211_tx_info is used in ath11k for
ath11k_skb_cb. The first function in the TX patch which rewrites it to
ath11k_skb_cb is already ath11k_mac_op_tx. No one else in the code path
must use it for something else before it reinitializes it. Otherwise the
data has to be considered uninitialized or corrupt.
But the ieee80211_tx_info.control shares exactly the same area as
ieee80211_tx_info.driver_data and ath11k is still using it. This results in
best case in a
ath11k c000000.wifi1: no vif found for mgmt frame, flags 0x0
or (slightly worse) in a kernel oops.
Instead, the interesting data must be moved first into the ath11k_skb_cb
and ieee80211_tx_info.control must then not be used anymore.

ath11k_peer_create() is called without its return value being checked,

Add packet log support for QCA6390, otherwise the data connection will stall
within a minute or so. Enable it via debugfs and use trace-cmd to capture the
pktlogs.
echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter
The mon status ring doesn't support interrupt so far, so host starts
a timer to reap this ring. The timer handler also reaps the
rxdma_err_dst_ring in case of monitor mode.
As QCA6390 requires bss created ahead of starting vdev, so check
vdev_start_delay for monitor mode.
For QCA6390, it uses wbm_desc_rel_ring to return descriptors.
It also uses rx_refill_buf_ring to fill mon buffer instead of
rxdma_mon_buf_ring.

QCA6390 does not support monitor mode at the moment so disable it altogether,
using a hack as mac80211 does not support disabling it otherwise. Add a boolean
to hw_params to know if hardware supports monitor mode.
IPQ8074 continues to support monitor mode normally.

As QCA6390 does not support mesh interfaces, move the interface_modes to
hw_params. Also create interface combinations dynamically so that it's easy to
change the values.
Now QCA6390 does not claim to support mesh interfaces to user space, but
IPQ8074 continues to do that.

For QCA6390, station vdev needs to delay startup but not for AP mode. On AP
mode vdev starts up immediately after bss peer is created in chanctx assignment
context.
This patch does not affect IPQ8074 family of devices.

In order to unify the tx status path, the hw 802.11 encapsulation flag
needs to survive the trip to the tx status call.
Since we don't have any free bits in info->flags, we need to move one.
IEEE80211_TX_INTFL_NEED_TXPROCESSING is only used internally in mac80211,
and only before the call into the driver.

The current API (which lets the driver turn on/off per vif directly) has a
number of limitations:
- it does not deal with AP_VLAN
- conditions for enabling (no tkip, no monitor) are only checked at
add_interface time
- no way to indicate 4-addr support
In order to address this, store offload flags in struct ieee80211_vif
(easy to extend for decap offload later). mac80211 initially sets the enable
flag, but gives the driver a chance to modify it before its settings are
applied. In addition to the .add_interface op, a .update_vif_offload op is
introduced, which can be used for runtime changes.
If a driver can't disable encap offload at runtime, or if it has some extra
limitations, it can simply override the flags within those ops.
Support for encap offload with 4-address mode interfaces can be enabled
by setting a flag from .add_interface or .update_vif_offload.

To enable raw mode tx/rx:

To enable software crypto:
insmod ath11k.ko crypto_mode=1
These modes could be helpful in debugging crypto related issues.

For QCA6390, only one pdev is created and this pdev manages both lmacs, thus
both rxdmas. So host needs to initialize all rxdma related rings for one pdev.
Another difference is for QCA6390, host fills rxbuf to firmware and firmware
further fills the rxbuf to rxbuf ring for each rxdma.

This is in fact 'disabled' in the spec, but there it's in a
place where that actually makes sense. In our internal data

previous commit just fixed a bug in that area.
Make this safer by inverting the polarity from 'disabled' to
'enabled'.

Currently need ptk/gtk wmi peer flags in wmi peer assoc cmd
are set based on the rsnie and wpaie of the bss from the bss list.
Since this bss list is not updated with current BSSID for AP mode,
we may not find bss from the bss list. Which results in ptk/gtk peer
flags are not set in the wmi peer assoc cmd. Due to this EAPOL frames
are going in data rates instead of management rates.
