net: airoha: Fix NPU RX DMA descriptor bits

2026-05-20T02:05:20Z

In an internal review from Airoha, it was notice that the RX DMA descriptor bits and mask are wrong. These values probably refer to an old NPU firmware never published. The previous value works correctly but it was reported that in some specific condition in mixed scenario with both Ethernet and WiFi offload it's possible that RX DMA descriptor signal wrong value with the problem to the RX ring or packets getting dropped. To handle these specific scenario, apply the new suggested bits mask from Airoha. Correct functionality of both AN7581 NPU and MT7996 variant were verified and confirmed working.

Pull ata fixes from Niklas Cassel: - Make sure that the issuing of a deferred non-NCQ command via workqueue feature is only used when mixing NCQ and non-NCQ commands to the same link (i.e. return value ATA_DEFER_LINK), and nothing else. This way we will not incorrectly try to use the feature for e.g. PATA drivers - The deferred non-NCQ command was stored in a per-port struct. When using Port Multipliers with FIS-Based Switching, we would thus needlessly defer commands to all other links. Store the deferred QC in a per-link struct, such that Port Multipliers with FBS will get the same performance as before - The issuing of a deferred non-NCQ command via workqueue feature broke support for Port Multipliers using Command-Based Switching. The issuing of a deferred non-NCQ command via workqueue feature is not compatible with the use of ap->excl_link, which PMPs with CBS use for fairness (using implicit round robin) * tag 'ata-7.1-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux: ata: libata-scsi: do not needlessly defer commands when using PMP with FBS ata: libata-scsi: do not use the deferred QC feature on PMPs with CBS ata: libata-scsi: do not use the deferred QC feature for ATA_DEFER_PORT ata: libata-scsi: improve readability of ata_scsi_qc_issue()

ata: libata-scsi: do not needlessly defer commands when using PMP with FBS

2026-05-18T10:26:51Z

The ACS specification does not allow a non-NCQ command to be issued while an NCQ command is outstanding. Commit 0ea84089dbf6 ("ata: libata-scsi: avoid Non-NCQ command starvation") introduced a feature where a deferred non-NCQ command gets issued from a workqueue. The design stores a single non-NCQ command per port. However, when using Port Multipliers (PMPs), specifically PMPs that support FIS-Based Switching (FBS), non-NCQ and NCQ commands can be mixed on the same port, just not for the same link, see e.g. ata_std_qc_defer() which is, and always has operated on a per-link basis. Therefore, move the deferred_qc from struct ata_port to struct ata_link. This way, when using a PMP with FBS, we will not needlessly defer commands to all other links, just because one link issued a non-NCQ command while having an NCQ command outstanding. Only commands for that specific link will be deferred. This is in line with how PMPs with FBS worked before commit 0ea84089dbf6 ("ata: libata-scsi: avoid Non-NCQ command starvation").

ata: libata-scsi: do not use the deferred QC feature on PMPs with CBS

2026-05-18T10:25:28Z

When using Port Multipliers (PMPs) with Command-Based Switching (CBS), you can only issue commands to one link at a time. For PMPs with CBS, there is already code to handle commands being sent to different links in sata_pmp_qc_defer_cmd_switch() using ap->excl_link. sata_sil24 also makes use of ap->excl_link. A user on the list reported that commit 0ea84089dbf6 ("ata: libata-scsi: avoid Non-NCQ command starvation") broke PMPs with CBS. The commit introduced code that stores a deferred qc in ap->deferred_qc, to later be issued via a workqueue. It turns out that this change is incompatible with the existing ap->excl_link handling used by PMPs with CBS. Thus, modify sata_pmp_qc_defer_cmd_switch() and sil24_qc_defer() to return ATA_DEFER_LINK_EXCL, and make sure that the deferred QC handling via workqueue is not used for this return value. This way, PMPs with CBS will work once again. Note that the starvation referenced in commit 0ea84089dbf6 ("ata: libata-scsi: avoid Non-NCQ command starvation") can only happen on libsas ports, and libsas does not support Port Multipliers, thus there is no harm of reverting back to the previous way of deferring commands for PMPs with CBS. Non-libsas ports connected to anything but a PMP with CBS (e.g. a normal drive or a PMP with FBS) will continue using the deferred workqueue, since it does result in lower completion latencies for non-NCQ commands, even though the workqueue is not strictly needed to avoid starvation for non-libsas ports. If we want to modify the scope of the workqueue issuing to also handle PMPs with CBS, then we should ensure that we can save both NCQ and non-NCQ commands in ap->deferred_qc, while also removing the existing PMP CBS handling using ap->excl_link, such that we don't duplicate features. While at it, also add a comment explaining how the ap->excl_link mechanism works.
