I see nothing in the driver/patch that will consolidate bp->dev->stats 
before your memcpy(). DMA transfert doesnt touch bp->dev->stats.

Please take a look at bnx2_get_stats()

+		memcpy(&bp->stats_extra, &bp->dev->stats,
+			sizeof(struct net_device_stats));

 		bnx2_reset_chip(bp, BNX2_DRV_MSG_CODE_RESET);
