2024-02-14igc: Remove temporary workaroundSasha Neftin
PHY_CONTROL register works as defined in the IEEE 802.3 specification (IEEE 802.3-2008 22.2.4.1). Tidy up the temporary workaround. User impact: PHY can now be powered down when the ethernet link is down. Testing hints: ip link set down <device> (or just disconnect the ethernet cable). Oldest tested NVM version is: 1045:740.

Change the code to use consistent types here to address the warning and make it more robust against workqueue interface changes. Side note: the use of a delayed workqueue for cleaning up TX descriptors is probably a bad idea since this introduces a noticeable delay. The driver currently does not appear to use BQL, but if one wanted to add that, this would have to be changed as well.

2024-02-12net: stmmac: xgmac: use #define for string constantsSimon Horman
The cited commit introduces and uses the string constants dpp_tx_err and dpp_rx_err. These are assigned to constant fields of the array dwxgmac3_error_desc. It has been reported that on GCC 6 and 7.5.0 this results in warnings such as: .../dwxgmac2_core.c:836:20: error: initialiser element is not constant { true, "TDPES0", dpp_tx_err }, I have been able to reproduce this using: GCC 7.5.0, 8.4.0, 9.4.0 and 10.5.0. But not GCC 13.2.0. So it seems this effects older compilers but not newer ones. As Jon points out in his report, the minimum compiler supported by the kernel is GCC 5.1, so it does seem that this ought to be fixed. It is not clear to me what combination of 'const', if any, would address this problem. So this patch takes of using #defines for the string constants Compile tested only.

Seth reported that on his side XDP traffic can not survive a round of down/up against i40e interface. Dmesg output was telling us that we were not able to disable the very first XDP ring. That was due to the fact that in i40e_vsi_stop_rings() in a pre-work that is done before calling i40e_vsi_wait_queues_disabled(), XDP Tx queues were not taken into the account.

2024-02-12ice: Remove and readd netdev during devlink reloadWojciech Drewek
Recent changes to the devlink reload (commit 9b2348e2d6c9 ("devlink: warn about existing entities during reload-reinit")) force the drivers to destroy devlink ports during reinit. Adjust ice driver to this requirement, unregister netdvice, destroy devlink port. ice_init_eth() was removed and all the common code between probe and reload was moved to ice_load(). During devlink reload we can't take devl_lock (it's already taken) and in ice_probe() we have to lock it. Use devl_* variant of the API which does not acquire and release devl_lock. Guard ice_load() with devl_lock only in case of probe.

2024-02-12ice: Add helper function ice_is_generic_macGrzegorz Nitka
E800 series devices have a couple of quirks: 1. Sideband control queues are not supported 2. The registers that the driver needs to program for the "Precision Time Protocol (PTP)" feature are different for E800 series devices compared to other devices supported by this driver. Both these require conditional logic based on the underlying device we are dealing with. The function ice_is_sbq_supported added by commit 8f5ee3c477a8 ("ice: add support for sideband messages") addresses (1). The same function can be used to address (2) as well but this just looks weird readability wise in cases that have nothing to do with sideband control queues: if (ice_is_sbq_supported(hw)) /* program register A */ else /* program register B */ For these cases, the function ice_is_generic_mac introduced by this patch communicates the idea/intention better. Also rework ice_is_sbq_supported to use this new function. As side-band queue is supported for E825C devices, it's mac_type is considered as generic mac_type.

2024-02-09lan966x: Fix crash when adding interface under a lagHoratiu Vultur
There is a crash when adding one of the lan966x interfaces under a lag interface. The issue can be reproduced like this: ip link add name bond0 type bond miimon 100 mode balance-xor ip link set dev eth0 master bond0 The reason is because when adding a interface under the lag it would go through all the ports and try to figure out which other ports are under that lag interface. And the issue is that lan966x can have ports that are NULL pointer as they are not probed. So then iterating over these ports it would just crash as they are NULL pointers. The fix consists in actually checking for NULL pointers before accessing something from the ports. Like we do in other places.
