Detailed Description

What ra8_wifi_c6link_setup needs to wire this backend to a link.

The link handle and its decode arena are caller-allocated because the whole ra8_c6link stack is heap-free; this backend opens the link inside ra8_wifi_backend::open. The transport seam is supplied already bound – by ra8_esp_hosted_c6link_bind on hardware, or by a co-processor model under test – so this backend stays independent of any one transport. The receive callback is the IP stack's L2 frame sink and may be null before the stack exists.

Invariant: link points at zero-initialised storage this backend may open.; transport has every row filled, exactly as ra8_c6link_open requires.; arena_bytes is at least k_ra8_c6link_arena_min.

Example:: ra8_wifi_c6link_cfg_t bcfg = { .link = &s_link, .arena = s_arena,

.arena_bytes = (uint32_t)sizeof s_arena };

(void)ra8_esp_hosted_c6link_bind(&bcfg.transport);
