Russell King says: ==================== Convert mv88e6xxx to phylink_pcs This series (previously posted with further patches on the 26 June as RFC) converts mv88e6xxx to phylink_pcs, and thus moves it from being a pre-March 2020 legacy driver. The first four patches lay the ground-work for the conversion by adding four new methods to the phylink_pcs operations structure: pcs_enable() - called when the PCS is going to start to be used pcs_disable() - called when the PCS is no longer being used pcs_pre_config() - called before the MAC configuration method pcs_post_config() - called after the MAC configuration method Both of these are necessary for some of the mv88e639x workarounds. We also add the ability to inform phylink of a change to the PCS state without involving the MAC later, by providing phylink_pcs_change() which takes a phylink_pcs structure rather than a phylink structure. phylink maintains which instance the PCS is conencted to, so internally it can do the right thing when the PCS is in-use. Then we provide some additional mdiobus and mdiodev accessors that we will be using in the new PCS drivers. The changes for mv88e6xxx follow, and the first one needs to be explicitly pointed out - we (Andrew and myself) have both decided that all possible approaches to maintaining backwards compatibility with DT have been exhaused - everyone has some objection to everything that has been proposed. So, after many years of trying, we have decided that this is just an impossibility, and with this patch, we are now intentionally and knowingly breaking any DT that does not specify the CPU and DSA port fixed-link parameters. Hence why Andrew has recently been submitting DT update patches. It is regrettable that it has come to this. Following this, we start preparing 88e6xxx for phylink_pcs conversion by padding the mac_select_pcs() DSA method, and the internal hooks to create and tear-down PCS instances. Rather than bloat the already very large mv88e6xxx_ops structure, I decided that it would be better that the new internal chip specific PCS methods are all grouped within their own structure - and this structure can be declared in the PCS drivers themselves. Then we have the actual conversion patches, one for each family of PCS. Lastly, we clean up the driver after conversion, removing all the now redundant code. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Now that mv88e6xxx is completely converted to using phylink_pcs support, we have no need for the serdes methods. Remove all this infrastructure. Also remove the __maybe_unused from mv88e6xxx_pcs_select(). Signed-off-by:

Add infrastructure for phylink_pcs to the mv88e6xxx driver. This involves adding a mac_select_pcs() hook so we can pass the PCS to phylink at the appropriate time, and a PCS initialisation function. As the various chip implementations are converted to use phylink_pcs, they are no longer reliant on the legacy phylink behaviour. We detect this by the use of this infrastructure, or the lack of any serdes. Signed-off-by:

As we now always use a fixed-link for DSA and CPU ports, we no longer need the hack in the Marvell code to make this work. Remove it. This is especially important with the conversion of DSA drivers to phylink_pcs, as the PCS code only gets called if we are using phylink for the port. Signed-off-by:

We now have a regmap cache which uses a maple tree to store the register state, this is a more modern data structure and the regmap level code using it makes a number of assumptions better tuned for modern hardware than those made by the rbtree cache type that the at9331 driver uses. Switch the ar9331 driver to use the more modern data structure. This should have minimal practical impact, it's mainly code modernisation. Signed-off-by:

Guillaume Nault says: ==================== net: Mark the sk parameter of routing functions as 'const'. The sk_getsecid security hook prevents the use of a const sk pointer in several routing functions. Since this hook should only read sk data, make its sk argument const (patch 1), then constify the sk parameter of various routing functions (patches 2-4).

The dev_rx_discards counter will increment by one when an interface is toggled up and down. The main reason is that the driver first sends a `NFP_NET_CFG_CTRL_ENABLE` configuration packet to the NIC to perform port initialisation when an interface is set up. But there is a race between physical link up and free list queue initialization which may lead to the configuration packet being discarded. To address this problem a new bit NFP_NET_CFG_CTRL_FREELIST_EN is added to perform free list initialisation on the NIC. The FREELIST_EN should be sent in advance to initialize free list queue. When a port is set to down, FREELIST_EN should be sent after CTRL_ENABLE to avoid packet discards. Signed-off-by:

Matthieu Baerts says: ==================== selftests: mptcp: join: pass args in new env vars In this series, Geliang did some refactoring in the mptcp_join.sh file. Patch 1 reduces the scope of some global env vars, only used by some tests: easier to deal with. Patch 2 uses a dedicated env var for fastclose case instead of re-using addr_nr_ns2 with embedded info, clearer. Patch 3 is similar but for the fullmesh case. Patch 4 moves a positional but optional argument of run_tests() to an env var like it has already been done with the other args, cleaner. ==================== Link: https://lore.kernel.org/r/20230712-upstream-net-next-20230712-selftests-mptcp-use-local-env-v1-0-f1c8b62fbf95@tessares.netSigned-off-by:
