For max bundle size 32, the bundle mask is not same with 8/16.
Change it to match the max bundle size of htc. Otherwise it
will not match with firmware, for example, when bundle count
is 17, then flags of ath10k_htc_hdr is 0x4, if without this
patch, it will be considered as non-bundled packet because it
does not have mask 0xF0, then trigger error message later:
payload length 56747 exceeds max htc length: 4088.
htc->max_msgs_per_htc_bundle is the min value of
HTC_HOST_MAX_MSG_PER_RX_BUNDLE and
msg->ready_ext.max_msgs_per_htc_bundle of ath10k_htc_wait_target,
it will be sent to firmware later in ath10k_htc_start, then
firmware will use it as the final max rx bundle count, in
WLAN.RMH.4.4.1-00029, msg->ready_ext.max_msgs_per_htc_bundle
is 32, it is same with HTC_HOST_MAX_MSG_PER_RX_BUNDLE, so the
final max rx bundle count will be set to 32 in firmware.
This patch only effect sdio chips.

For tcp RX, the quantity of tcp acks to remote is 1/2 of the quantity
of tcp data from remote, then it will have many small length packets
on TX path of sdio bus, then it reduce the RX packets's bandwidth of
tcp.
This patch enable napi on RX path, then the RX packet of tcp will not
feed to tcp stack immeditely from mac80211 since GRO is enabled by
default, it will feed to tcp stack after napi complete, if rx bundle
is enabled, then it will feed to tcp stack one time for each bundle
of RX. For example, RX bundle size is 32, then tcp stack will receive
one large length packet, its length is neary 1500*32, then tcp stack
will send a tcp ack for this large packet, this will reduce the tcp
acks ratio from 1/2 to 1/32. This results in significant performance
improvement for tcp RX.
Tcp rx throughout is 240Mbps without this patch, and it arrive 390Mbps
with this patch. The cpu usage has no obvious difference with and
without NAPI.

After the firmware crashes ath10k recovers via ieee80211_reconfig(),
which eventually leads to firmware configuration and including the
encryption keys. However, because there is no new auth/assoc and
4-way-handshake, and firmware set the authorize flag after
4-way-handshake, so the authorize flag in firmware is not set in
firmware without 4-way-handshake. This will lead to a failure of data
transmission after recovery done when using encrypted connections like
WPA-PSK. Set authorize flag after installing keys to firmware will fix
the issue.
This was noticed by testing firmware crashing using simulate_fw_crash
debugfs file.

So far, frames were forwarded regardless of the FCS correctness leading
to userspace applications listening on the monitor mode interface to
receive potentially broken frames, even with the "fcsfail" flag unset.
By default, with the "fcsfail" flag of a monitor mode interface
unset, frames with FCS errors should be dropped. With this patch, the
fcsfail flag is taken into account correctly.

When the BDF download QMI message has the end field set to 1, it signals
the end of the transfer, and triggers the firmware to do a CRC check. The
BDFs for msm8998 devices fail this check, yet the firmware is happy to
still use the BDF. It appears that this error is not caught by the
downstream drive by concidence, therefore there are production devices
in the field where this issue needs to be handled otherwise we cannot
support wifi on them. So, attempt to detect this scenario as best we can
and treat it as non-fatal.

When ath10k_qmi_init() fails, the error handling does not free the irq
resources, which causes an issue if we EPROBE_DEFER as we'll attempt to
(re-)register irqs which are already registered.
Fix this by doing a power off since we just powered on the hardware, and
freeing the irqs as error handling.

For RX, it has two parts, one is to read data from sdio, another
is to indicate the packets to upper stack. Recently it has only
one thread to do all RX things, it results that it is sequential
for RX and low throughout, change RX to parallel for the two parts
will increase throughout.
This patch move the indication to a workqueue, it results in
significant performance improvement on RX path.
Udp rx throughout is 200Mbps without this patch, and it arrives
400Mbps with this patch.

The real max rx bundle is decided in ath10k_htc_wait_target(),
it is the min value of HTC_HOST_MAX_MSG_PER_RX_BUNDLE and the value reported
from firmware. So this change shouldn't cause any regressions with other
hardware supported by ath10k.

The existing implementation of initiating multiple sdio transfers for
receive bundling is slowing down the receive speed. Combining the
transfers using a bundle method would be ideal.
The transmission utilization ratio for sdio bus for small packet is
slow, because the space and time cost for sdio bus is same for large
length packet and small length packet. So the speed of data for large
length packet is higher than small length.

The `ar_usb` field of `ath10k_usb_pipe_usb_pipe` objects
are initialized to point to the containing `ath10k_usb` object
according to endpoint descriptors read from the device side, as shown
below in `ath10k_usb_setup_pipe_resources`:
for (i = 0; i < iface_desc->desc.bNumEndpoints; ++i) {
endpoint = &iface_desc->endpoint[i].desc;
// get the address from endpoint descriptor
pipe_num = ath10k_usb_get_logical_pipe_num(ar_usb,
endpoint->bEndpointAddress,
&urbcount);
......
// select the pipe object
pipe = &ar_usb->pipes[pipe_num];
// initialize the ar_usb field
pipe->ar_usb = ar_usb;
}
The driver assumes that the addresses reported in endpoint
descriptors from device side to be complete. If a device is
malicious and does not report complete addresses, it may trigger
NULL-ptr-deref `ath10k_usb_alloc_urb_from_pipe` and
`ath10k_usb_free_urb_to_pipe`.
This patch fixes the bug by preventing potential NULL-ptr-deref.

When hardware rfkill is enabled in the firmware it will report the
capability via using WMI_TLV_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY
event to the host. ath10k will check the capability, and if it is enabled then
ath10k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When
the firmware detects hardware rfkill is enabled by the user, it will report it
via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath10k receives the event it will
send wmi command WMI_PDEV_SET_PARAM to the firmware to enable/disable the radio
and also notifies cfg80211.
We can't power off the device when rfkill is enabled, as otherwise the
firmware would not be able to detect GPIO changes and report them to the
host. So when rfkill is enabled, we need to keep the firmware running.
Tested with QCA6174 PCI with firmware
WLAN.RM.4.4.1-00109-QCARMSWPZ-1.

This patch restores the old behavior that read
the chip_id on the QCA988x before resetting the
chip. This needs to be done in this order since
the unsupported QCA988x AR1A chips fall off the
bus when resetted. Otherwise the next MMIO Op
after the reset causes a BUS ERROR and panic.

[18120.533631] ath10k_pci 0000:01:00.0: timed out waiting for offchannel skb cf0e3f00
This bug appears to have been added between 4.0 (which works for us),
and 4.4, which does not work.
I think this is because the tx-offchannel logic gets in a loop when
ath10k_mac_tx_frm_has_freq(ar) is false, so pkt is never actually
sent to the firmware for transmit.
This patch fixes the problem on 4.9 for me, and now HS20 clients
can work again with my firmware.

In a multiradio board with one QCA9984 and one AR9987
after enabling the crashdump with module parameter

This is due to ath10k_hw_mem_layout is not defined for AR9987.

Check for the ramdump_size before allocation memory.

Since ath10k_mac_tx_push_txq() can be called from process context, we
must explicitly disable softirqs before the call into mac80211.
By calling ieee80211_tx_dequeue_ni() instead of ieee80211_tx_dequeue()
we make sure softirqs are always disabled even in the case when
ath10k_mac_tx_push_txq() is called from process context.
Calling ieee80211_tx_dequeue_ni() with softirq's already disabled
(e.g., from softirq context) should be safe as the local_bh_disable()
and local_bh_enable() functions (called from ieee80211_tx_dequeue_ni)
are fully reentrant.
