smatch reports that: fw.c:1997 rtw89_append_probe_req_ie() error: uninitialized symbol 'ret'. This can be a issue only if no band is supported by the chip, but it is impossible. So, it is still safe without this patch. Signed-off-by:

Commit dae0978d ("dt: bindings: net: add qcom,ath11k.yaml") obviously adds qcom,ath11k.yaml, but the file entry in MAINTAINERS, added with commit fcda1cb8 ("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. Repair this file reference in QUALCOMM ATHEROS ATH11K WIRELESS DRIVER, and put it in alphabetic order while at it.

This patch increases the number of RX-FIFOs to 3 and the max TX-FIFO depth to 16. This leads to the following default ring configuration. CAN-2.0 mode: | FIFO setup: TEF: 0x400: 8*12 bytes = 96 bytes | FIFO setup: RX-0: FIFO 1/0x460: 32*20 bytes = 640 bytes | FIFO setup: RX-1: FIFO 2/0x6e0: 32*20 bytes = 640 bytes | FIFO setup: RX-2: FIFO 3/0x960: 16*20 bytes = 320 bytes | FIFO setup: TX: FIFO 4/0xaa0: 8*16 bytes = 128 bytes | FIFO setup: free: 224 bytes CAN-FD mode: | FIFO setup: TEF: 0x400: 4*12 bytes = 48 bytes | FIFO setup: RX-0: FIFO 1/0x430: 16*76 bytes = 1216 bytes | FIFO setup: RX-1: FIFO 2/0x8f0: 4*76 bytes = 304 bytes | FIFO setup: TX: FIFO 3/0xa20: 4*72 bytes = 288 bytes | FIFO setup: free: 192 bytes With the previously added ethtool ring configuration support the RAM on the chip can now be runtime configured between RX and TX buffers.

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.

So far the configuration of the hardware FIFOs is hard coded and depend only on the selected CAN mode (CAN-2.0 or CAN-FD).

To add a filter for GTP-C, specify enc_dst_port = 2123, e.g.: tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \ enc_dst_port 2123 action mirred egress redirect dev $VF1_PR Note: outer IPv6 offload is not supported yet. Note: GTP-U with no payload offload is not supported yet. ICE COMMS package is required to create a filter as it contains GTP profiles. Changes in iproute2 [1] are required to be able to add GTP netdev and use GTP-specific options (QFI and PDU type).

In case external PHY is used, we need to take care of embedded PHY. Since there are no methods to disable this PHY from the MAC side and keeping RMII reference clock, we need to suspend it.

Before adding yet another possibly contended atomic_long_t, it is time to add per-cpu storage for existing ones: dev->tx_dropped, dev->rx_dropped, and dev->rx_nohandler Because many devices do not have to increment such counters, allocate the per-cpu storage on demand, so that dev_get_stats() does not have to spend considerable time folding zero counters. Note that some drivers have abused these counters which were supposed to be only used by core networking stack. v4: should use per_cpu_ptr() in dev_get_stats() (Jakub) v3: added a READ_ONCE() in netdev_core_stats_alloc() (Paolo) v2: add a missing include (reported by kernel test robot <lkp@intel.com>) Change in netdev_core_stats_alloc() (Jakub) Signed-off-by:Eric Dumazet <edumazet@google.com> Cc: jeffreyji <jeffreyji@google.com> Reviewed-by:

Simon Horman says: ==================== nfp: preliminary support for NFP-3800 This series is the first step to add support to the NFP driver for the new NFP-3800 device. 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. More work is needed to drive the new NFP-3800 device after this first batch of patches the foundation is prepared for the follow up work.

NFP3800 has slightly different queue controller range bounds. Use the static chip data instead of defines. This commit still assumes unchanged descriptor format. Later datapath changes will allow adjusting for descriptor accounting. Signed-off-by:

Jakub Kicinski authored
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. Use nfp_dev_info to store queue controller parameters. Signed-off-by:
