Your mcbin-ss is A8K AX or A8K B0? On AX revisions we do not have FC

support in firmware.

How do I tell? I don't want to remove the heatsink, and I don't see anything
in MV-S111188-00E. I didn't grab a copy of the Errata before I accidentally let
me extranet access expire.

You can devmem 0xF2400240(Device ID Status Register).
#define A8040_B0_DEVICE_ID      0x8045
#define A8040_AX_DEVICE_ID      0x8040
#define A7040_B0_DEVICE_ID      0x7045
#define A7040_AX_DEVICE_ID      0x7040
#define A3900_A1_DEVICE_ID      0x6025
#define CN9130_DEVICE_ID        0x7025
