sfc: Add workspace for GMAC bug workaround to MCDI MAC_STATS buffer
Due to a hardware bug in the SFC9000 family, the firmware must
transfer raw GMAC statistics to host memory before aggregating them
into the cooked (speed-independent) MAC statistics. Extend the stats
buffer to support this.
The length of the buffer is explicit in the MAC_STATS command, so this
change is backward-compatible on both sides.
