Pages for Rx buffers are allocated in cas_page_alloc() using either
GFP_ATOMIC or GFP_KERNEL. Memory allocated with GFP_KERNEL/GFP_ATOMIC can't
come from highmem and so there's no need to kmap() them. Just use
page_address() instead. This makes the variable 'addr' unnecessary, so
remove it too.
Note that kmap_atomic() disables preemption and page-fault processing,
but page_address() doesn't. When removing uses of kmap_atomic(), one has to
check if the code being executed between the map/unmap implicitly depends
on page-faults and/or preemption being disabled. If yes, then code to
disable page-faults and/or preemption should also be added for functional
correctness. That however doesn't appear to be the case here, so just
page_address() is used.
I don't have hardware, so this change has only been compile tested.

kmap_atomic() is being deprecated in favor of kmap_local_page(). Replace
kmap_atomic() and kunmap_atomic() with kmap_local_page() and kunmap_local()
respectively.
Note that kmap_atomic() disables preemption and page-fault processing, but
kmap_local_page() doesn't. When converting uses of kmap_atomic(), one has
to check if the code being executed between the map/unmap implicitly
depends on page-faults and/or preemption being disabled. If yes, then code
to disable page-faults and/or preemption should also be added for
functional correctness. That however doesn't appear to be the case here,
so just kmap_local_page() is used.
Also note that the page being mapped is not allocated by the driver, and so
the driver doesn't know if the page is in normal memory. This is the reason
kmap_local_page() is used as opposed to page_address().
I don't have hardware, so this change has only been compile tested.

kmap_atomic() is being deprecated in favor of kmap_local_page(). Replace
the map-memcpy-unmap usage pattern (done using k[un]map_atomic()) with
memcpy_from_page(), which internally uses kmap_local_page() and
kunmap_local(). This renders the variables 'data' and 'vaddr' unnecessary,
and so remove these too.
Note that kmap_atomic() disables preemption and page-fault processing, but
kmap_local_page() doesn't. When converting uses of kmap_atomic(), one has

Also note that the page being mapped is not allocated by the driver, and so
the driver doesn't know if the page is in normal memory. This is the reason
kmap_local_page() is used (via memcpy_from_page()) as opposed to
page_address().

====================
net: lan966x: Extend xdp support
Extend the current support of XDP in lan966x with the action XDP_TX and
XDP_REDIRECT.
The first patches just prepare the things such that it would be easier
to add XDP_TX and XDP_REDIRECT actions. Like adding XDP_PACKET_HEADROOM,
introduce helper functions, use the correct dma_dir for the page pool
The last 2 patches introduce the XDP actions XDP_TX and XDP_REDIRECT.
v4->v5:
- add iterator declaration inside for loops
- move the scope of port inside the function lan966x_fdma_rx_alloc_page_pool
- create union for skb and xdpf inside struct lan966x_tx_dcb_buf
v3->v4:
- use napi_consume_skb instead of dev_kfree_skb_any
- arrange members in struct lan966x_tx_dcb_buf not to have holes
- fix when xdp program is added the check for determining if page pool
needs to be recreated was wrong
- change type for len in lan966x_tx_dcb_buf to u32
v2->v3:
- make sure to update rxq memory model
- update the page pool direction if there is any xdp program
- in case of action XDP_TX give back to reuse the page
- in case of action XDP_REDIRECT, remap the frame and make sure to
unmap it when is transmitted.
v1->v2:
- use skb_reserve of using skb_put and skb_pull
- make sure that data_len doesn't include XDP_PACKET_HEADROOM

Extend lan966x XDP support with the action XDP_TX. In this case when the
received buffer needs to execute XDP_TX, the buffer will be moved to the
TX buffers. So a new RX buffer will be allocated.
When the TX finish with the frame, it would give back the buffer to the
page pool.

To add support for XDP_TX it is required to be able to write to the DMA
area therefore it is required that the pages will be mapped using
DMA_BIDIRECTIONAL flag.
Therefore check if there are any xdp programs on the interfaces and in
that case set DMA_BIDRECTIONAL otherwise use DMA_FROM_DEVICE.
Therefore when a new XDP program is added it is required to redo the
page_pool.

Currently when a frame was transmitted, it is required to unamp the
frame that was transmitted. The length of the frame was taken from the
transmitted skb. In the future we might not have an skb, therefore store
the length skb directly in the lan966x_tx_dcb_buf and use this one to
unamp the frame.
While at this, also arrange the members in lan966x_tx_dcb_buf not to
have any holes.

net: TC protocol all support in Sparx5 IS2 VCAP
This provides support for the TC flower filters 'protocol all' clause in
the Sparx5 IS2 VCAP.
It builds on top of the initial IS2 VCAP support found in these series:
https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/
https://lore.kernel.org/all/20221109114116.3612477-1-steen.hegelund@microchip.com/
https://lore.kernel.org/all/20221111130519.1459549-1-steen.hegelund@microchip.com/
https://lore.kernel.org/all/20221117213114.699375-1-steen.hegelund@microchip.com/
Functionality:
==============
As the configuration for the Sparx5 IS2 VCAP consists of one (or more)
keyset(s) for each lookup/port per traffic classification, it is not
always possible to cover all protocols with just one ordinary VCAP rule.
To improve this situation the driver will try to find out what keysets a
rule will need to cover a TC flower "protocol all" filter and then compare
this set of keysets to what the hardware is currently configured for.
In case multiple keysets are needed then the driver can create a rule per
rule size (e.g. X6 and X12) and use a mask on the keyset type field to
allow the VCAP to match more than one keyset with just one rule.
This is possible because the keysets that have the same size typically has
many keys in common, so the VCAP rule keys can make a common match.
The result is that one TC filter command may create multiple IS2 VCAP rules
of different sizes that have a type field with a masked type id.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- Sparx5 IS0 VCAP support
- TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support
Version History:
================
v2 Fixed a NULL return value compiler warning.
Moved the new vcap_find_actionfield function a bit up in the file.
v1 Initial version

This allows support of TC protocol all for the Sparx5 IS2 VCAP.
This is done by creating multiple rules that covers the rule size and
traffic types in the IS2.
Each rule size (e.g X16 and X6) may have multiple keysets and if there are
more than one the type field in the VCAP rule will be wildcarded to support
these keysets.

10M/100M/1000M; YT8531S Fiber function with support of 100M/1000M;
and YT8531S Combo function that supports auto detection of media type.

and Toke suggest reverting the patch 2e0de6366ac16 and making
it stronger, so do this first.

Vladimir Oltean says:
====================
Remove dsa_priv.h
After working on the "Autoload DSA tagging driver when dynamically
changing protocol" series:
https://patchwork.kernel.org/project/netdevbpf/cover/20221115011847.2843127-1-vladimir.oltean@nxp.com/
it became clear to me that the situation with DSA headers is a bit
messy, and I put the tagging protocol driver macros in a pretty random
temporary spot in dsa_priv.h.
Now is the time to make the net/dsa/ folder a bit more organized, and to
make tagging protocol driver modules include just headers they're going
to use.
Another thing is the merging and cleanup of dsa.c and dsa2.c. Before,
dsa.c had 589 lines and dsa2.c had 1817 lines. Now, the combined dsa.c
has 1749 lines, the rest went to some other places.
Sorry for the set size, I know the rules, but since this is basically
code movement for the most part, I thought more patches are better.

The last remnants in dsa_priv.h are a netlink-related definition for
which we create a new header, and DSA_MAX_NUM_OFFLOADING_BRIDGES which
is only used from dsa.c, so move it there.
Some inclusions need to be adjusted now that we no longer have headers
included transitively from dsa_priv.h.

tag_8021q definitions are all over the place. Some are exported to
linux/dsa/8021q.h (visible by DSA core, taggers, switch drivers and
everyone else), and some are in dsa_priv.h.
Move the structures that don't need external visibility into tag_8021q.c,
and the ones which don't need the world or switch drivers to see them
into tag_8021q.h.
We also have the tag_8021q.h inclusion from switch.c, which is basically
the entire reason why tag_8021q.c was built into DSA in commit
8b6e638b4be2 ("net: dsa: build tag_8021q.c as part of DSA core").
I still don't know how to better deal with that, so leave it alone.

There are some definitions in dsa_priv.h which are only used from
slave.c. So move them to slave.c.

The previous change moved the code into the larger file (dsa2.c) to
minimize the delta. Rename that now to dsa.c, and create dsa.h, where
all related definitions from dsa_priv.h go.
