The implementations of xmit_xdp_frame get the xdpi parameter of type
struct mlx5e_xdp_info for the sole purpose of calling
mlx5e_xdpi_fifo_push() on success.
This commit moves this call outside of xmit_xdp_frame, shifting this
responsibility to the caller. It will allow more fine-grained handling
of XDP info for cases when an xdp_frame is fragmented.

Use page_pool_set_dma_addr() to store the DMA address of a page inside
struct page, in order to avoid passing struct mlx5e_dma_info to XDP
handlers. Previously, struct mlx5e_dma_info was used to pass both the
DMA address and the page, and it worked well for the single-fragment
case.
When XDP multi buffer is in use, and a fragmented xdp_frame has to be
transmitted, the driver needs to know the DMA addresses of fragments,
however, the array of fragments in struct skb_shared_info doesn't
contain them. In order to pass the DMA addresses, the driver puts them
into struct page itself, which is accessible from the array of fragments
in struct skb_shared_info. The existing XDP handlers are modified to
remove the dependency on struct mlx5e_dma_info.

XDP multi buffer implementation in the kernel assumes that all fragments
have the same size. bpf_xdp_frags_increase_tail uses this assumption to
get the size of the last fragment, and __xdp_build_skb_from_frame uses
it to calculate truesize as nr_frags * xdpf->frame_sz.
The current implementation of mlx5e uses fragments of different size in
non-linear legacy RQ. Specifically, the last fragment can be larger than
the others. It's an optimization for packets smaller than MTU.
This commit adapts mlx5e to the kernel limitations and makes it use
fragments of the same size, in order to add support for XDP multi
buffer. The change is applied only if XDP is active, otherwise the old
optimization still applies.

mlx5e_skb_from_cqe_nonlinear creates an xdp_buff first, putting the
first fragment as the linear part, and the rest of fragments as
fragments to struct skb_shared_info in the tailroom. Then it creates an
SKB in place, based on the xdp_buff. The XDP program is not called in
this commit yet.
This commit contains no functional change, except the SKB is built over
the whole frag_stride of the first fragment, instead of the minimal size
required (headroom, data and skb_shared_info).

Again new complaints surfaced that we had broken the ABI here,
although previously all the userspace tools had agreed that it
was their mistake and fixed it. Yet now there are cases (e.g.
RHEL) that want to run old userspace with newer kernels, and
thus are broken.
Since this is a bit of a whack-a-mole thing, change the whole
extensibility scheme of rfkill to no longer just rely on the
message lengths, but instead require userspace to opt in via a
new ioctl to a given maximum event size that it is willing to
understand.
By default, set that to RFKILL_EVENT_SIZE_V1 (8), so that the
behaviour for userspace not calling the ioctl will look as if
it's just running on an older kernel.

Per-flow mirroring with the VCAP IS2 TCAM (in itself handled as an
offload for tc-flower) is done by setting the MIRROR_ENA bit from the
action vector of the filter. The packet is mirrored to the port mask
configured in the ANA:ANA:MIRRORPORTS register (the same port mask as
the destinations for port-based mirroring).
Functionality was tested with:
tc qdisc add dev swp3 clsact
tc filter add dev swp3 ingress protocol ip \
flower skip_sw ip_proto icmp \
action mirred egress mirror dev swp1
and pinging through swp3, while seeing that the ICMP replies are
mirrored towards swp1.

Some VCAP filters utilize resources which are global to the switch, like
for example VCAP IS2 policers take an index into a global policer pool.
In commit c9a7fe1238e5 ("net: mscc: ocelot: add action of police on
vcap_is2"), Xiaoliang expressed this by hooking into the low-level
ocelot_vcap_filter_add_to_block() and ocelot_vcap_block_remove_filter()
functions, and allocating/freeing the policers from there.
Evaluating the code, there probably isn't a better place, but we'll need
to do something similar for the mirror ports, and the code will start to
look even more hacked up than it is right now.
Create two ocelot_vcap_filter_{add,del}_aux_resources() functions to
contain the madness, and pollute less the body of other functions such
as ocelot_vcap_filter_add_to_block().

Ocelot switches perform port-based ingress mirroring if
ANA:PORT:PORT_CFG field SRC_MIRROR_ENA is set, and egress mirroring if
the port is in ANA:ANA:EMIRRORPORTS.
Both ingress-mirrored and egress-mirrored frames are copied to the port
mask from ANA:ANA:MIRRORPORTS.
So the choice of limiting to a single mirror port via ocelot_mirror_get()
and ocelot_mirror_put() may seem bizarre, but the hardware model doesn't
map very well to the user space model. If the user wants to mirror the
ingress of swp1 towards swp2 and the ingress of swp3 towards swp4, we'd
have to program ANA:ANA:MIRRORPORTS with BIT(2) | BIT(4), and that would
make swp1 be mirrored towards swp4 too, and swp3 towards swp2. But there
are no tc-matchall rules to describe those actions.
Now, we could offload a matchall rule with multiple mirred actions, one
per desired mirror port, and force the user to stick to the multi-action
rule format for subsequent matchall filters. But both DSA and ocelot
have the flow_offload_has_one_action() check for the matchall offload,
plus the fact that it will get cumbersome to cross-check matchall
mirrors with flower mirrors (which will be added in the next patch).
As a result, we limit the configuration to a single mirror port, with
the possibility of lifting the restriction in the future.
Frames injected from the CPU don't get egress-mirrored, since they are
sent with the BYPASS bit in the injection frame header, and this
bypasses the analyzer module (effectively also the mirroring logic).
I don't know what to do/say about this.
Functionality was tested with:
tc qdisc add dev swp3 clsact
tc filter add dev swp3 ingress \
matchall skip_sw \
action mirred egress mirror dev swp1
and pinging through swp3, while seeing that the ICMP replies are

In early LinkStreet silicon (e.g. 6095/6185), the per-VLAN STP states
were kept in the VTU - there was no concept of a SID. Later, the
information was split into two tables, where the VTU only tracked
memberships and deferred the STP state tracking to the STU via a
pointer (SID). This meant that a group of VLANs could share the same
STU entry. Most likely, this was done to align with MSTP (802.1Q-2018,
Clause 13), which is built on this principle.
While the VTU is still 4k lines on most devices, the STU is capped at
64 entries. This means that the current stategy, updating STU info
whenever a VTU entry is updated, can not easily support MSTP because:
- The maximum number of VIDs would also be capped at 64, as we would
have to allocate one SID for every VTU entry - even if many VLANs
would effectively share the same MST.
- MSTP updates would be unnecessarily slow as you would have to
iterate over all VLANs that share the same MST.
In order to support MSTP offloading in the future, manage the STU as a
separate entity from the VTU.
Only add support for newer hardware with separate VTU and
STU. VTU-only devices can also be supported, but essentially this
requires a software implementation of an STU (fanning out state
changed to all VLANs tied to the same MST).

An example: When a port's MST state changes from forwarding to

be done in the VLANs that are managed by the MSTI in question.

Make it possible to change the port state in a given MSTI by extending
the bridge port netlink interface (RTM_SETLINK on PF_BRIDGE).The
proposed iproute2 interface would be:
bridge mst set dev <PORT> msti <MSTI> state <STATE>
Current states in all applicable MSTIs can also be dumped via a
corresponding RTM_GETLINK. The proposed iproute interface looks like
this:
$ bridge mst
port msti
vb1 0
state forwarding
100
state disabled
vb2 0
state forwarding
100
state forwarding
The preexisting per-VLAN states are still valid in the MST
mode (although they are read-only), and can be queried as usual if one
is interested in knowing a particular VLAN's state without having to
care about the VID to MSTI mapping (in this example VLAN 20 and 30 are
bound to MSTI 100):
$ bridge -d vlan
port vlan-id
vb1 10

Allow the user to switch from the current per-VLAN STP mode to an MST
mode.
Up to this point, per-VLAN STP states where always isolated from each
other. This is in contrast to the MSTP standard (802.1Q-2018, Clause
13.5), where VLANs are grouped into MST instances (MSTIs), and the
state is managed on a per-MSTI level, rather that at the per-VLAN
level.
Perhaps due to the prevalence of the standard, many switching ASICs
are built after the same model. Therefore, add a corresponding MST
mode to the bridge, which we can later add offloading support for in a
straight-forward way.
For now, all VLANs are fixed to MSTI 0, also called the Common
Spanning Tree (CST). That is, all VLANs will follow the port-global
state.
Upcoming changes will make this actually useful by allowing VLANs to
be mapped to arbitrary MSTIs and allow individual MSTI states to be
changed.

The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for ints and unsigned
ints.

All WQ types moved to using the fragmented allocation API
for coherent memory. Contiguous API is not used anymore.
Remove it, reduce the number of exported functions.

On tuple offload del command, tuples are tried to be removed twice
from the hashtable, once directly via mlx5_tc_ct_entry_remove_from_tuples()
and a second time in the following mlx5_tc_ct_entry_put()->
mlx5_tc_ct_entry_del()->mlx5_tc_ct_entry_remove_from_tuples() call.
This doesn't cause any issue since rhashtable first checks if the
removed object exists in the hashtable.
Remove the extra mlx5_tc_ct_entry_remove_from_tuples().

It can be calculated via function mlx5dr_ste_get_hw_ste().
Very simple and lightweight, no need to use a dedicated member.
Reduce 8 bytes from struct mlx5dr_ste and its size is 48 bytes now.

Remove chunk_size in struct mlx5dr_icm_chunk and use
chunk->size instead.
Remove ste_arr/hw_ste_arr/miss_list since they can be accessed
from htbl->chunk pointer, no need to keep a copy.
This commit reduces 28 bytes from struct mlx5dr_ste_htbl and its
size is 32 bytes now.

Target to reduce the memory consumption in large scale of flow rules.
They can be calculated quickly from buddy memory pool.
1. num_of_entries calls dr_icm_pool_get_chunk_num_of_entries().
2. byte_size calls dr_icm_pool_get_chunk_byte_size().
Use chunk size in dr_icm_chunk to speed up and the one in dr_ste_htbl
will be removed in the upcoming commit.
This commit reduce 8 bytes from struct mlx5_dr_icm_chunk and its
current size is 56 bytes.
