2022-03-16mt76: fix monitor mode crash with sdio driverDeren Wu
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!

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.
