Hi all, 

A very limited review below.

+	/* get capabilities of particular feature */
+	ENA_ADMIN_GET_FEATURE = 8,

Instead /* get capabilities  SHOULD BE:  /* set capabilities .....
+
+	/* get capabilities of particular feature */
+	ENA_ADMIN_SET_FEATURE = 9,
+
..


+int ena_com_set_hash_ctrl(struct ena_com_dev *ena_dev)
+{
+	struct ena_com_admin_queue *admin_queue = &ena_dev->admin_queue;
...

You set ret=-EINVAL, but you do not use this ret as you immediately return 0 in the next line, which is the end of the method. Either return ret or return -EINVAL.
+	if (unlikely(ret)) {
+		ena_trc_err("Failed to set hash input. error: %d\n", ret);
+		ret = -EINVAL;
+	}
+
+	return 0;
+}
+



+
+/* ena_com_set_mmio_read_mode - Enable/disable the mmio reg read mechanism
+ * @ena_dev: ENA communication layer struct


Instead realess_supported: SHOULD BE: readless_supported

+void ena_com_set_mmio_read_mode(struct ena_com_dev *ena_dev,
