2022-03-17iwlwifi: mei: fix building iwlmeiArnd Bergmann
Building iwlmei without CONFIG_CFG80211 causes a link-time warning: ld.lld: error: undefined symbol: ieee80211_hdrlen >>> referenced by net.c >>> net/wireless/intel/iwlwifi/mei/net.o:(iwl_mei_tx_copy_to_csme) in archive drivers/built-in.a Add an explicit dependency to avoid this.

Commit dae0978d4174 ("dt: bindings: net: add qcom,ath11k.yaml") obviously adds qcom,ath11k.yaml, but the file entry in MAINTAINERS, added with commit fcda1cb81663 ("MAINTAINERS: add DT bindings files for ath10k and ath11k") then refers to qcom,ath11k.txt. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference.

2022-03-13can: mcp251xfd: add RX IRQ coalescing supportMarc Kleine-Budde
This patch adds RX IRQ coalescing support to the driver. The mcp251xfd chip doesn't support proper hardware based coalescing, so this patch tries to implemented it in software. The RX-FIFO offers a "FIFO not empty" interrupt, which is used if no coalescing is active. With activated RX IRQ coalescing the "FIFO not empty" interrupt is disabled in the RX IRQ handler and the "FIFO half full" or "FIFO full interrupt" (depending on RX max coalesced frames IRQ) is used instead. To avoid RX CAN frame starvation a hrtimer is setup with RX coalesce usecs IRQ,on timer expiration the "FIFO not empty" is enabled again. Support for ethtool configuration is added in the next patch.

In this first series the goal is to clean up small issues found while adding support for the new device, prepare an abstraction of the differences between the already supported devices and the new Kestrel device and add the new PCI ID. * Patch 1/11 and 2/11 starts by removing some dead code and incorrect assumptions found while working Kestrel support. Patch 3/11, 4/11 and 5/11 cleans up and prepares for adding the new PCI ID for Kestrel. * Patches 6/11, 7/11, 8/11, 9/11, 10/11 adds, plumb and populates a device information structure to abstract the differences between the existed supported devices (NFP-4000, NFP-5000 and NFP-6000) and the new device (NFP3800). * Finally patch 11/11 adds the new PCI ID for Kestrel.

2022-03-11nfp: parametrize QCP offset/size using dev_infoJakub Kicinski
The queue controller (QCP) is accessed based on a device specific offset. The NFP3800 device also supports more queues. Furthermore, the NFP3800 VFs also access the QCP differently to how the NFP6000 VFs accesses it, though still indirectly. Fortunately, we can remove the offset all together for both VF types. This is safe for NFP6000 VFs since the offset was effectively a wrap around and only used for convenience to have it set the same as the NFP6000 PF.

2022-03-11nfp: remove pessimistic NFP_QCP_MAX_ADD limitsChristo du Toit
Multiple writes cause intermediate pointer values that do not end on complete TX descriptors. The QCP peripheral on the NFP provides a number of access modes. In some access modes, the maximum amount to add must be restricted to a 6bit value. The particular access mode used by _nfp_qcp_ptr_add() has no such restrictions, so the "< NFP_QCP_MAX_ADD" test is unnecessary. Note that trying to add more that the configured ring size in a single add will cause a QCP overflow, caught and handled by the QCP peripheral.

In review for commit 8ee7ec4890e2b ("net: ipa: embed interconnect array in the power structure"), Jakub Kicinski suggested that a follow-up patch use struct_size() when computing the size of the IPA power structure, which ends with a flexible array member. Do that.
