Detailed Description

Per-queue configuration descriptor for ra8_eth_gwca_configure_queue.

Populated by the caller and passed to configure_queue; holds the user-facing GWDCC fields plus the chain-head pointer that goes into the matching LINKFIX entry.

Note

GWDCC.SM (Synchronization Mode) is always programmed to 00b (Normal mode, full descriptor write-back) – it is NOT a source-MAC selector. Which port's frames land in this queue is decided by the MFWD forwarding fabric (FWPBFCSDC0), not by the GWCA queue config.
