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.

To support multiple users referencing the same fragment, 'pp_frag_count' is renamed to 'pp_ref_count', transitioning pp pages from fragment management to reference count management after draining based on the suggestion from [1]. The idea is that the concept of fragmenting exists before the page is drained, and all related functions retain their current names. However, once the page is drained, its management shifts to being governed by 'pp_ref_count'. Therefore, all functions associated with that lifecycle stage of a pp page are renamed.

Alexander Lobakin says: ==================== idpf: add get/set for Ethtool's header split ringparam Currently, the header split feature (putting headers in one smaller buffer and then the data in a separate bigger one) is always enabled in idpf when supported. One may want to not have fragmented frames per each packet, for example, to avoid XDP frags. To better optimize setups for particular workloads, add ability to switch the header split state on and off via Ethtool's ringparams, as well as to query the current status. There's currently only GET in the Ethtool Netlink interface for now, so add SET first. I suspect idpf is not the only one supporting this. ==================== Link: https://lore.kernel.org/r/20231212142752.935000-1-aleksander.lobakin@intel.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

idpf supports the header split feature and that feature is always enabled by default. However, for flexibility reasons and to simplify some scenarios, it would be useful to have the support for switching the header split off (and on) from the userspace. Address that need by adding the user config parameter, the functions for disabling (or enabling) the header split feature, and calls to them from the Ethtool ringparam callbacks. It still is enabled by default if supported by the hardware.

Follow up commit 9690ae60 ("ethtool: add header/data split indication") and add the set part of Ethtool's header split, i.e. ability to enable/disable header split via the Ethtool Netlink interface. This might be helpful to optimize the setup for particular workloads, for example, to avoid XDP frags, and so on. A driver should advertise ``ETHTOOL_RING_USE_TCP_DATA_SPLIT`` in its ops->supported_ring_params to allow doing that. "Unknown" passed from the userspace when the header split is supported means the driver is free to choose the preferred state.

tcf_idr_insert_many will replace the allocated -EBUSY pointer in tcf_idr_check_alloc with the real action pointer, exposing it to all operations. This operation is only needed when the action pointer is created (ACT_P_CREATED). For actions which are bound to (returned 0), the pointer already resides in the idr making such operation a nop. Even though it's a nop, it's still not a cheap operation as internally the idr code walks the idr and then does a replace on the appropriate slot. So if the action was bound, better skip the idr replace entirely.

Instead of relying only on the idrinfo->lock mutex for bind/alloc logic, rely on a combination of rcu + mutex + atomics to better scale the case where multiple rtnl-less filters are binding to the same action object. Action binding happens when an action index is specified explicitly and an action exists which such index exists. Example: tc actions add action drop index 1 tc filter add ... matchall action drop index 1 tc filter add ... matchall action drop index 1 tc filter add ... matchall action drop index 1 tc filter ls ... filter protocol all pref 49150 matchall chain 0 filter protocol all pref 49150 matchall chain 0 handle 0x1 not_in_hw action order 1: gact action drop random type none pass val 0 index 1 ref 4 bind 3 filter protocol all pref 49151 matchall chain 0 filter protocol all pref 49151 matchall chain 0 handle 0x1 not_in_hw action order 1: gact action drop random type none pass val 0 index 1 ref 4 bind 3 filter protocol all pref 49152 matchall chain 0 filter protocol all pref 49152 matchall chain 0 handle 0x1 not_in_hw action order 1: gact action drop random type none pass val 0 index 1 ref 4 bind 3 When no index is specified, as before, grab the mutex and allocate in the idr the next available id. In this version, as opposed to before, it's simplified to store the -EBUSY pointer instead of the previous alloc + replace combination. When an index is specified, rely on rcu to find if there's an object in such index. If there's none, fallback to the above, serializing on the mutex and reserving the specified id. If there's one, it can be an -EBUSY pointer, in which case we just try again until it's an action, or an action. Given the rcu guarantees, the action found could be dead and therefore we need to bump the refcount if it's not 0, handling the case it's in fact 0. As bind and the action refcount are already atomics, these increments can happen without the mutex protection while many tcf_idr_check_alloc race to bind to the same action instance. In case binding encounters a parallel delete or add, it will return -EAGAIN in order to try again. Both filter and action apis already have the retry machinery in-place. In case it's an unlocked filter it retries under the rtnl lock.

Christian Marangi says: ==================== net: phy: at803x: cleanup The intention of this big series is to try to cleanup the big at803x PHY driver. It currently have 3 different family of PHY in it. at803x, qca83xx and qca808x. The current codebase required lots of cleanup and reworking to make the split possible as currently there is a greater use of adding special function matching the phy_id. This has been reworked to make the function actually generic and make the change only in more specific one. The result is the addition of micro additional function but that is for good as it massively simplify splitting the driver later. Consider that this is all in preparation for the addition of qca807x PHY driver that will also uso some of the functions of at803x. Subsequent series will come with the actual PHY split and other required cleanup. This is only to start the process with minor changes. Changes v4: - Improve at8031_probe function Changes v3: - Add Reviewed-by tag from Andrew - Split patch 10 (at8031 rename) to rename and move Changes v2: - Drop split part due to series too big - Split changes even more - Fix problem pointed out by Russell (flawed reworked function logic) - Add Reviewed-by tag from Andrew - Minor rework to prevent further code duplication for cdt ==================== Signed-off-by: David S.
