     14 -------- |  |
                 | /
                 |/

N.B. For cases of non-MLD connection, we set our link instance-0
active with link_id 0. So, our code flow can be compatible between
non-MLD connection and MLD connection.

Based on above, we tweak entire driver architecture first. But, we don't
dynamically enable multiple links here. That will be handled separately.
Most of the things changed here are changing flows to iterate all active
links and read bss_conf/link_sta data according to target link. And, for
cases of scan, ROC, WOW, we use instance-0 to deal with the request.

There are some things listed below, which work for now but need to extend
before multiple active links.
1. tx path
select suitable link instance among multiple active links
2. rx path
determine rx link by PPDU instead of always link instance-0
3. CAM
apply MLD pairwise key to any active links dynamically

Besides, PS code cannot easily work along with tweaking architecture. With
supporting MLO flag (currently false), we disable PS first and will fix it
by another commit in the following.

Merge branch 'net-fib_rules-add-dscp-selector-support'

Ido Schimmel says:

====================
net: fib_rules: Add DSCP selector support

Currently, the kernel rejects IPv4 FIB rules that try to match on the
upper three DSCP bits:

 # ip -4 rule add tos 0x1c table 100
 # ip -4 rule add tos 0x3c table 100
 Error: Invalid tos.

The reason for that is that historically users of the FIB lookup API
only populated the lower three DSCP bits in the TOS field of the IPv4
flow key ('flowi4_tos'), which fits the TOS definition from the initial
IPv4 specification (RFC 791).

This is not very useful nowadays and instead some users want to be able
to match on the six bits DSCP field, which replaced the TOS and IP
precedence fields over 25 years ago (RFC 2474). In addition, the current
behavior differs between IPv4 and IPv6 which does allow users to match
on the entire DSCP field using the TOS selector.

Recent patchsets made sure that callers of the FIB lookup API now
populate the entire DSCP field in the IPv4 flow key. Therefore, it is
now possible to extend FIB rules to match on DSCP.

This is done by adding a new DSCP attribute which is implemented for
both IPv4 and IPv6 to provide user space programs a consistent behavior
between both address families.

The behavior of the old TOS selector is unchanged and IPv4 FIB rules
using it will only match on the lower three DSCP bits. The kernel will
reject rules that try to use both selectors.

Patch #1 adds the new DSCP attribute but rejects its usage.

Patches #2-#3 implement IPv4 and IPv6 support.

Patch #4 allows user space to use the new attribute.

Patches #5-#6 add selftests.

ld: vmlinux.o: in function `mp_dmabuf_devmem_alloc_netmems':

>> ld: vmlinux.o:(.static_call_sites+0xb824): undefined reference to `__SCK__tp_func_page_pool_state_hold'

The root cause is that in this configuration, traces are enabled but the
page_pool specific trace_page_pool_state_hold is not registered.

There is no reason to build the dmabuf memory provider when
CONFIG_PAGE_POOL is not present, as it's really a provider to the
page_pool.

In fact the whole NET_DEVMEM is RX path-only at the moment, so we can
make the entire config dependent on the PAGE_POOL.

Note that this may need to be revisited after/while devmem TX is
added,  as devmem TX likely does not need CONFIG_PAGE_POOL. For now this
build fix is sufficient.

1 RX queue by default. User can increase the RX queues via ethtool,
e.g. 'ethtool -L ethx rx <N>'

The series also adds regmap and regfield support to some of the
ALE registers. It adds Policer/Classifier registers and fields.

Converting the existing ALE control APIs to regfields can be a separate
exercise.

Some helper functions are added to read/write to the Policer/Classifier
registers and a default Classifier setup function is added that
routes packets based on their PCP/DSCP priority to different RX queues.

10 months agonet/mlx5: Skip HotPlug check on sync reset using hot reset

method of hot reset this check can be skipped as Hotplug is supported on

10 months agonet/mlx5: fs, add support for no append at software level

net/mlx5: fs, add support for no append at software level

Native capability for some steering engines lacks support for adding an
additional match with the same value to the same flow group. To accommodate
the NO APPEND flag in these scenarios, we include the new rule in the
existing flow table entry (fte) without immediate hardware commitment. When
a request is made to delete the corresponding hardware rule, we then commit
the pending rule to hardware.

Only one pending rule is supported because NO_APPEND is primarily used
during replacement operations. In this scenario, a rule is initially added.
When it needs replacement, the new rule is added with NO_APPEND set. Only
after the insertion of the new rule is the original rule deleted.
