Data Fields
uint32_t	id
	Right-aligned accept ID (11- or 29-bit).
uint32_t	mask
	ID bit mask: 1 = must match, 0 = don't care.
bool	extended
	true = 29-bit extended ID, false = 11-bit std.
bool	rtr
	true = match remote frames, false = data frames.
uint8_t	target_rx
	Destination RX FIFO index (0..1).

Detailed Description

One Acceptance-Filter-List (AFL) rule: hardware ID/mask match plus an RX-FIFO routing target.

Each rule programs one CFDGAFL slot. The controller accepts an inbound frame when, for some active rule, (frame_id & mask) == (id & mask) and the frame's IDE flag equals extended and its RTR flag equals rtr; matched frames are routed into RX FIFO target_rx instead of being dropped. id and mask are right-aligned identifiers: an 11-bit standard value when extended is false, a 29-bit extended value when true.

cppcheck cannot see tests/ so it flags every field as unused; each member is read in ra8_canfd_set_accept_filter in libs/ra8_hal/src/ra8_canfd_afl.c.

Invariant: If extended is false, id and mask fit in 11 bits.; If extended is true, id and mask fit in 29 bits.; target_rx < k_ra8_canfd_rx_fifo_count.
