As 'channel' is declared as u16, the following expression is always false.
channel < 0
So we can remove unnecessary 'always false' statement.

In this step, the read/write routines for the descriptors are converted
to use __le32 quantities, thus a lot of casts can be removed. Callback
routines still use the 8-bit arrays, but these are changed within the
specified routine.

As a first step in the conversion, the macros that set the RX and TX
descriptors are converted to static inline routines, and the names are
changed from upper to lower case. To minimize the changes in a given
step, the input descriptor information is left as as a byte array
(u8 *), even though it should be a little-endian word array (__le32 *).
That will be changed in the next patch.
Several places where checkpatch.pl complains about a space after a cast
and other warnings are fixed.

This driver uses a set of local macros to manipulate the RX and TX
descriptors, which are all little-endian quantities. These macros
are replaced by the bitfield macros le32p_replace_bits() and
le32_get_bits(). In several places, the macros operated on an entire
32-bit word. In these cases, a direct read or replacement is used.

Some sdio chips of rome QCA6174's regulatory domain code of EEPROM is
empty, then ath_is_world_regd will return false for this case, and
it will lead function __ath_reg_dyn_country not work, thus the regdomain
will not update for NL80211_REGDOM_SET_BY_COUNTRY_IE type, it result
ath10k set the same regdomain/reg_5ghz_ctl/reg_2ghz_ctl to firmware,
then the tx power will not changed with different regdomain's AP. The
regulatory domain code of EEPROM of some QCA6174 PCIE chip is 0x6c, it
means world wide regdomain, for this chip, it does not have the issue.
For empty reulatory domain code chip, set it to world regulatory domain
in functio ath_regd_sanitize, then it will fix the issue.
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00029.

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.
Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

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.

wmi_init command. But as per the current initialization sequence, REO ring
configurations are done only after wmi_init command is sent.

Guard interval value which comes from VHT_SIG_A TLV has a mapping
where value 0 corresponds to LGI, 1 and 3 corresponds to SGI.
Value 3 which is SGI(0.4us) in VHT was incorrectly mapped to a GI
of 3.2us(only applicable in HE) resulting in incorrect rx GI stats.
Fixing the mapping.

This patch will add the support to control the transmit power
for traffic to a station associated with the AP.
Underlying firmware will enforce that the maximum tx power will
be based on the regulatory requirements. If the user given
transmit power is greater than the allowed tx power in the given
channel, then the firmware will use the maximum tx power in the
same channel.
Max and Min tx power values will depends on number of tx chain
masks. The allowed tx power range values are from 6 to 23.
When 0 is sent to the firmware as tx power, it will revert to
the default tx power for the station.

Currenly in delba process calling ath11k_peer_rx_tid_delete() updates
reo with desc invalid and add tid queue to the flush list. If station
send data traffic without addba req and before tid flush, hw gives
those packets as invalid desc reo error. Since we are dropping these
invalid desc packets results in traffic stall.
This patch fix this issue by updating the reo queue with bawindow size 1
instead of tid removal in delba process.

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.

It is observed that ath11k STA mode UL throughput is low.
This is due to packets delivered to FW from TCL instead of TQM.

properly configuring the TCL address search type and ast_hash.
