Pull staging driver updates from Greg KH:
"This is the "big" staging driver update for 6.11-rc1. Not really all
that much happened this release cycle, just lots of tiny cleanups,
overall about 3000 lines removed, so the cleanups were worth it.
Included in here are:
- loads of rtl8723bs driver cleanups
- lots of rtl8192e driver cleanups
- vc04_services reworks and cleanups as that codebase gets slowly
evolved into something that will make it into the "real" part of
the kernel hopefully soon.
- other tiny staging driver cleanups
All of these have been in linux-next for a while with no reported
issues"

For channel contexts, mac80211 currently uses the cfg80211
chandef struct (control channel, center freq(s), width) to
define towards drivers and internally how these behave. In
fact, there are _two_ such structs used, where the min_def
can reduce bandwidth according to the stations connected.
Unfortunately, with EHT this is longer be sufficient, at
least not for all hardware. EHT requires that non-AP STAs
that are connected to an AP with a lower bandwidth than it
(the AP) advertises (e.g. 160 MHz STA connected to 320 MHz
AP) still be able to receive downlink OFDMA and respond to
trigger frames for uplink OFDMA that specify the position
and bandwidth for the non-AP STA relative to the channel
the AP is using. Therefore, they need to be aware of this,
and at least for some hardware (e.g. Intel) this awareness
is in the hardware. As a result, use of the "same" channel
may need to be split over two channel contexts where they
differ by the AP being used.
As a first step, introduce a concept of a channel request
('chanreq') for each interface, to control the context it
requests. This step does nothing but reorganise the code,
so that later the AP's chandef can be added to the request
in order to handle the EHT case described above.

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the
channel context handling.

multiple structures contains a ieee80211_rts structure, which is required to
have at least two byte alignment, but are annotated with a __packed attribute
to force single-byte alignment:
staging/vt6656/rxtx.h:98:1: warning: alignment 1 of 'struct vnt_rts_g' is less than 2 [-Wpacked-not-aligned]

I see no reason why the structure itself would be misaligned, and all members
have at least two-byte alignment within the structure, so use the same
constraint on the sturcture itself.

A limit is also placed in vnt_tx_context of MAX_TOTAL_SIZE_WITH_ALL_HEADERS
limiting size.

Create room for vnt_tx_short_buf_head in sk_buff and vnt_tx_usb_header.
The struct ieee80211_mgmt is not longer in the header and is at
the initial skb->data point.

mac80211 can provide space for the driver to put a tx header on
the skb buffer instead coping the entire frame on to a local
buffer with the header.
To use this extra_tx_headroom must be set in mac80211 with the largest
possible header which is struct vnt_tx_buffer.
The driver has 8 possible combinations of tx header size which
are found in vnt_get_hdr_size replacing vnt_mac_hdr_pos.
