Detailed Description

State block for ra8_eth_gwca_default_open / _send / _recv.

Caller-owned block holding the LINKFIX table + RX/TX chain heads + per-queue head/tail cursors that the default-path API tracks. Sized for one TX + one RX queue.

Layout policy:

All descriptor + buffer storage is caller-supplied (BSS-resident arrays) so the HAL doesn't pull in any allocator. Caller picks ring depths and slot sizes at static-allocation time.
