Currently when NL80211_SCAN_FLAG_COLOCATED_6GHZ is set in the scan flags,
in addition to the co-located APs, PSC channels in the 6 GHz band would
also be scanned if the user space has asked for it. In other words, the

reported in the RNR IE.

wifi: mac80211: mesh fast xmit support
Previously, fast xmit only worked on interface types where initially a
sta lookup is performed, and a cached header can be attached to the sta,
requiring only some fields to be updated at runtime.
This technique is not directly applicable for a mesh device type due
to the dynamic nature of the topology and protocol. There are more
addresses that need to be filled, and there is an extra header with a
dynamic length based on the addressing mode.
Change the code to cache entries contain a copy of the mesh subframe header +
bridge tunnel header, as well as an embedded struct ieee80211_fast_tx, which
contains the information for building the 802.11 header.
Add a mesh specific early fast xmit call, which looks up a cached entry and
adds only the mesh subframe header, before passing it over to the generic
fast xmit code.
To ensure the changes in network are reflected in these cached headers,
flush affected cached entries on path changes, as well as other conditions
that currently trigger a fast xmit check in other modes (key changes etc.)
This code is loosely based on a previous implementation by:

wifi: rtl8xxxu: Support new chip RTL8710BU aka RTL8188GU
This chip is found in cheap "free driver" USB adapters from Aliexpress.
Initially they pretend to be a CD-ROM containing the driver for Windows.
"Ejecting" switches the device to wifi mode.
Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps.
This chip is more unique than other Realtek chips:
* The registers at addresses 0x0-0xff, which all the other chips use,
can't be used here. New registers at 0x8000-0x80ff must be used
instead. And it's not a simple matter of adding 0x8000: 0x2
(REG_SYS_FUNC) became 0x8004, 0x80 (REG_MCU_FW_DL) became 0x8090,
etc.
* Also there are a few new registers which must be accessed indirectly
because their addresses don't fit in 16 bits. No other chips seem to
have these.
* The vendor driver compiles to 8188gu.ko, but the code calls the chip
RTL8710B(U) pretty much everywhere, including messages visible to the
user.
Another difference compared to the other chips supported by rtl8xxxu is
that it has a new PHY status struct, or three of them actually, from
which we extract the RSSI, among other things. This is not unique,
though, just new. The chips supported by rtw88 also use it.

wifi: iwlwifi: fw: pnvm: fix uefi reduced TX power loading
There are a number of issues here:
* if trans->reduce_power_loaded is already true, we call
iwl_trans_set_reduce_power() with an uninitialized len
value
* in this case we also clobber a previous load/setting
* if iwl_uefi_get_reduced_power() returns an ERR_PTR() we
try to kfree() it
Move the iwl_trans_set_reduce_power() call into the success
case only to fix these issues.

If there's a rate->index that maps inside the range but
to an uninitialized value, then that's also a bad rate,
avoid printing "(nil)" in that case and rather print the
"BAD_RATE" string instead as in the else branch.

cppcheck reports
[drivers/net/wireless/intel/iwlwifi/mvm/rs.c:2686]: (warning) Assignment of function parameter has no effect outside the function. Did you forget dereferencing it?
The setting of the 'sta' parameter is not needed. In the if-check that sets it
to NULL, mvm_sta is also set to NULL. Then the next statement checks if
mvm_sta is NULL and does an early return. So remove setting sta.
