====================
Convert net selftests to run in unique namespace (Part 3)

Here is the 3rd part of converting net selftests to run in unique namespace.
This part converts all srv6 and fib tests.

Note that patch 06 is a fix for testing fib_nexthop_multiprefix.

Here is the part 1 link:
https://lore.kernel.org/netdev/20231202020110.362433-1-liuhangbin@gmail.com

a33e9da347 selftests/net: fix grep checking for fib_nexthop_multiprefix
When running fib_nexthop_multiprefix test I saw all IPv6 test failed.
e.g.

 ]# ./fib_nexthop_multiprefix.sh
 TEST: IPv4: host 0 to host 1, mtu 1300                              [ OK ]
 TEST: IPv6: host 0 to host 1, mtu 1300                              [FAIL]

 With -v it shows

The reason is when CONFIG_IPV6_SUBTREES is not enabled, rt6_fill_node() will
not put RTA_SRC info. After fix:

268531be21 net: mdio: mdio-bcm-unimac: Delay before first poll
With a clock interval of 400 nsec and a 64 bit transactions (32 bit
preamble & 16 bit control & 16 bit data), it is reasonable to assume
the mdio transaction will take 25.6 usec. Add a 30 usec delay before
the first poll to reduce the chance of a 1000-2000 usec sleep.

Reduce the timeout from 1000ms to 100ms as it is unlikely for the bus
to take this long.

Jakub Kicinski says:

====================
tools: ynl-gen: fill in the gaps in support of legacy families

Fill in the gaps in YNL C code gen so that we can generate user
space code for all genetlink families for which we have specs.

The two major changes we need are support for fixed headers and
support for recursive nests.

For fixed header support - place the struct for the fixed header
directly in the request struct (and don't bother generating access
helpers). The member of a fixed header can't be too complex, and
also are by definition not optional so the user has to fill them in.
The YNL core needs a bit of a tweak to understand that the attrs
may now start at a fixed offset, which is not necessarily equal
to sizeof(struct genlmsghdr).

Dealing with nested sets is much harder. Previously we'd gen
the nested structs as:

 struct outer {
   struct inner inner;
 };

If structs are recursive (e.g. inner contains outer again)
we must break this chain and allocate one of the structs
dynamically (store a pointer rather than full struct).

If recursive struct is placed in the op directly - the first

aa75783b95 tools: ynl-gen: re-sort ignoring recursive nests
We try to keep the structures and helpers "topologically sorted",
to avoid forward declarations. When recursive nests are at play
we need to sort twice, because structs which end up being marked
as recursive will get a full set of forward declarations, so we
should ignore them for the purpose of sorting.

38329fcfb7 tools: ynl-gen: record information about recursive nests
Track which nests are recursive. Non-recursive nesting gets
rendered in C as directly nested structs. For recursive
ones we need to put a pointer in, rather than full struct.

Track this information, no change to generated code, yet.

The description in Marvell's functional specification seems to be wrong.
To enable MII, we need to set GENCONF_CTRL0_PORT3_RGMII, while for RGMII
we need to clear it. This is also how U-Boot handles it.

Ahmed Zaki says:

====================
Support symmetric-xor RSS hash

Patches 1 and 2 modify the get/set_rxh ethtool API to take a pointer to
struct of parameters instead of individual params. This will allow future
changes to the uAPI-shared struct ethtool_rxfh without changing the
drivers' API.

Patch 3 adds the support at the Kernel level, allowing the user to set a
symmetric-xor RSS hash for a netdevice via:

    # ethtool -X eth0 hfunc toeplitz symmetric-xor

and clears the flag via:

    # ethtool -X eth0 hfunc toeplitz

The "symmetric-xor" is set in a new "input_xfrm" field in struct
ethtool_rxfh. Support for the new "symmetric-xor" flag will be later sent
to the "ethtool" user-space tool.

Patch 4 fixes a long standing bug with the ice hash function register
values. The bug has been benign for now since only (asymmetric) Toeplitz
hash (Zero) has been used.

Patches 5 and 6 lay some groundwork refactoring. While the first is
mainly cosmetic, the second is needed since there is no more room in the
previous 64-bit RSS profile ID for the symmetric attribute introduced in
the next patch.

Finally, patches 7 and 8 add the symmetric-xor support for the ice
(E800 PFs) and the iAVF drivers.

352e9bf238 ice: enable symmetric-xor RSS for Toeplitz hash function
Allow the user to set the symmetric Toeplitz hash function via:

    # ethtool -X eth0 hfunc toeplitz symmetric-xor

All existing RSS configurations will be converted to symmetric unless they
have a non-symmetric field (other than IP src/dst and L4 src/dst ports)
used for hashing. The driver will reject a new RSS configuration if such
a field is requested.

The hash function in the E800 NICs is set per-VSI and a specific AQ
command is needed to modify the hash function. Use the AQ command to
enable setting the symmetric Toeplitz RSS hash function for any VSI
in the new ice_set_rss_hfunc().

When the Symmetric Toeplitz hash function is used, the hardware sets the
input set of the RSS (Toeplitz) algorithm to be the XOR of the fields
index by HSYMM and the fields index by the INSET registers. We use this
to create a symmetric hash by setting the HSYMM registers to point to
their counterparts in the INSET registers:

 HSYMM [src_fv] = dst_fv;
 HSYMM [dst_fv] = src_fv;

where src_fv and dst_fv are the indexes of the protocol's src and dst
fields.

The flow director and RSS blocks use separate methods to generate a
unique 64 bit ID for the flow. This is not extendable, especially for
the RSS that already uses all 64 bit space.

Refactor the flow generation API so that the ID is generated within
ice_flow_add_prof(). The FD and RSS blocks caches the generated ID for
later use.

dc6e44c9d6 ice: refactor RSS configuration
Refactor the driver to use a communication data structure for RSS
config. To do so we introduce the new ice_rss_hash_cfg struct, and then
pass it as an argument to several functions.

Also introduce enum ice_rss_cfg_hdr_type to specify a more granular and
flexible RSS configuration:

ICE_RSS_OUTER_HEADERS - take outer layer as RSS input set
ICE_RSS_INNER_HEADERS - take inner layer as RSS input set
ICE_RSS_INNER_HEADERS_W_OUTER_IPV4 - take inner layer as RSS input set for
                                     packet with outer IPV4
ICE_RSS_INNER_HEADERS_W_OUTER_IPV6 - take inner layer as RSS input set for
                                     packet with outer IPV6
ICE_RSS_ANY_HEADERS - try with outer first then inner (same as the
		      behaviour without this change)

Finally, move the virtchnl_rss_algorithm enum to be with the other RSS
related structures in the virtchnl.h file.

There should be no functional change due to this patch.

20f73b60bb ice: fix ICE_AQ_VSI_Q_OPT_RSS_* register values
Fix the values of the ICE_AQ_VSI_Q_OPT_RSS_* registers. Shifting is
already done when the values are used, no need to double shift. Bug was
not discovered earlier since only ICE_AQ_VSI_Q_OPT_RSS_TPLZ (Zero) is
currently used.

Also, rename ICE_AQ_VSI_Q_OPT_RSS_XXX to ICE_AQ_VSI_Q_OPT_RSS_HASH_XXX
for consistency.

13e59344fb net: ethtool: add support for symmetric-xor RSS hash
Symmetric RSS hash functions are beneficial in applications that monitor
both Tx and Rx packets of the same flow (IDS, software firewalls, ..etc).
Getting all traffic of the same flow on the same RX queue results in
higher CPU cache efficiency.

A NIC that supports "symmetric-xor" can achieve this RSS hash symmetry
by XORing the source and destination fields and pass the values to the
RSS hash algorithm.

The user may request RSS hash symmetry for a specific algorithm, via:

    # ethtool -X eth0 hfunc <hash_alg> symmetric-xor

or turn symmetry off (asymmetric) by:

    # ethtool -X eth0 hfunc <hash_alg>

The specific fields for each flow type should then be specified as usual
via:
    # ethtool -N|-U eth0 rx-flow-hash <flow_type> s|d|f|n

dcd8dbf9e7 net: ethtool: get rid of get/set_rxfh_context functions
Add the RSS context parameters to struct ethtool_rxfh_param and use the
get/set_rxfh to handle the RSS contexts as well.

This is part 2/2 of the fix suggested in [1]:

 - Add a rss_context member to the argument struct and a capability
   like cap_link_lanes_supported to indicate whether driver supports
   rss contexts, then you can remove *et_rxfh_context functions,
   and instead call *et_rxfh() with a non-zero rss_context.

fb6e30a725 net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool ops
The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters
as direct function arguments. This will force us to change the API (and
all drivers' functions) every time some new parameters are added.

This is part 1/2 of the fix, as suggested in [1]:

- First simplify the code by always providing a pointer to all params
   (indir, key and func); the fact that some of them may be NULL seems
   like a weird historic thing or a premature optimization.
   It will simplify the drivers if all pointers are always present.

 - Then make the functions take a dev pointer, and a pointer to a
   single struct wrapping all arguments. The set_* should also take
   an extack.

The second patch is new to this series and reverts the behavior of the
dpaa2-switch driver to not ask for object replay upon offloading so that
we avoid the errors encountered when a VLAN is installed multiple times
on the same port.

f24a49a375 dpaa2-switch: do not ask for MDB, VLAN and FDB replay
Starting with commit 4e51bf44a0 ("net: bridge: move the switchdev
object replay helpers to "push" mode") the switchdev_bridge_port_offload()
helper was extended with the intention to provide switchdev drivers easy
access to object addition and deletion replays. This works by calling
the replay helpers with non-NULL notifier blocks.

In the same commit, the dpaa2-switch driver was updated so that it
passes valid notifier blocks to the helper. At that moment, no
regression was identified through testing.

In the meantime, the blamed commit changed the behavior in terms of
which ports get hit by the replay. Before this commit, only the initial
port which identified itself as offloaded through
switchdev_bridge_port_offload() got a replay of all port objects and
FDBs. After this, the newly joining port will trigger a replay of
objects on all bridge ports and on the bridge itself.

This behavior leads to errors in dpaa2_switch_port_vlans_add() when a
VLAN gets installed on the same interface multiple times.

The intended mechanism to address this is to pass a non-NULL ctx to the
switchdev_bridge_port_offload() helper and then check it against the
port's private structure. But since the driver does not have any use for
the replayed port objects and FDBs until it gains support for LAG
offload, it's better to fix the issue by reverting the dpaa2-switch
driver to not ask for replay. The pointers will be added back when we
are prepared to ignore replays on unrelated ports.
