mt7921s driver may receive frames with fragment buffers. If there is a CTS packet received in monitor mode, the payload is 10 bytes only and need 6 bytes header padding after RXD buffer. However, only RXD in the first linear buffer, if we pull buffer size RXD-size+6 bytes with skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in __skb_pull(). To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to 256 to make sure all MCU operation in linear buffer. [ 52.007562] kernel BUG at include/linux/skbuff.h:2313!

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.

The 1st patch is by me and fixes the freeing of a skb in the vxcan driver (initially added in this net-next window). The remaining 12 patches are also by me and target the mcp251xfd driver. The first patch fixes a printf modifier (initially added in this net-next window). The remaining patches add ethtool based ring and RX/TX IRQ coalescing support to the driver. ==================== Signed-off-by:

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.
