+  Remark about CAN FD (flexible data rate) support:
+
+  Generally the handling of CAN FD is very similar to the formerly described
+  examples. The new CAN FD capable CAN controllers support two different
+  bitrates for the arbitration phase and the payload phase of the CAN FD frame
+  and up to 64 bytes of payload. This extended payload length breaks all the
+  kernel interfaces (ABI) which heavily rely on the CAN frame with fixed eight
+  bytes of payload (struct can_frame) like the CAN_RAW socket. Therefore e.g.
+  the CAN_RAW socket supports a new socket option CAN_RAW_FD_FRAMES that
+  switches the socket into a mode that allows the handling of CAN FD frames
+  and (legacy) CAN frames simultaneously (see section 4.1.5).
+
+  The struct canfd_frame is defined in include/linux/can.h:
+
+    struct canfd_frame {
+            canid_t can_id;  /* 32 bit CAN_ID + EFF/RTR/ERR flags */
+            __u8    len;     /* frame payload length in byte (0 .. 64) */

+            __u8    data[64] __attribute__((aligned(8)));
+    };
+
+  The struct canfd_frame and the existing struct can_frame have the can_id,
+  the payload length and the payload data at the same offset inside their
+  structures. This allows to handle the different structures very similar.
+  When the content of a struct can_frame is copied into a struct canfd_frame
+  all structure elements can be used as-is - only the data[] becomes extended.
+
+  When introducing the struct canfd_frame it turned out that the data length
+  code (DLC) of the struct can_frame was used as a length information as the
+  length and the DLC has a 1:1 mapping in the range of 0 .. 8. To preserve
+  the easy handling of the length information the canfd_frame.len element
+  contains a plain length value from 0 .. 64. So both canfd_frame.len and
+  can_frame.can_dlc are equal and contain a length information and no DLC.
+  For details about the distinction of CAN and CAN FD capable devices and
+  the mapping to the bus-relevant data length code (DLC), see chapter 6.6.
+
+  The length of the two CAN(FD) frame structures define the maximum transfer
+  unit (MTU) of the CAN(FD) network interface and skbuff data length. Two

+  or CAN FD frames and can process them the same way.
+
+  When sending to CAN devices make sure that the device is capable to handle
+  CAN FD frames by checking if the device maximum transfer unit is CANFD_MTU.
+  The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.

+  6.6 CAN FD (flexible data rate) driver support
+
+  CAN FD capable CAN controllers support two different bitrates for the
+  arbitration phase and the payload phase of the CAN FD frame. Therefore a
+  second bittiming has to be specified in order to enable the CAN FD bitrate.
+
+  Additionally CAN FD capable CAN controllers support up to 64 bytes of
+  payload. The representation of this length in can_frame.can_dlc and
+  canfd_frame.len for userspace applications and inside the Linux network
+  layer is a plain value from 0 .. 64 instead of the CAN 'data length code'.
+  The data length code was a 1:1 mapping to the payload length in the legacy
+  CAN frames anyway. The payload length to the bus-relevant DLC mapping is
+  only performed inside the CAN drivers, preferably with the helper
+  functions can_dlc2len() and can_len2dlc().
+
+  The CAN netdevice driver capabilities can be distinguished by the network
+  devices maximum transfer unit (MTU):
+
+  MTU = 16 (CAN_MTU)   => sizeof(struct can_frame)   => 'legacy' CAN device
+  MTU = 72 (CANFD_MTU) => sizeof(struct canfd_frame) => CAN FD capable device
+
+  The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.
+  N.B. CAN FD capable devices can also handle and send legacy CAN frames.
+
+  FIXME: Add details about the CAN FD controller configuration when available.

+
+Energy Efficient Ethernet(EEE) enables IEEE 802.3 MAC sublayer along
+with a family of Physical layer to operate in the Low power Idle(LPI)
+mode. The EEE mode supports the IEEE 802.3 MAC operation at 100Mbps,
+1000Mbps & 10Gbps.
+
+The LPI mode allows power saving by switching off parts of the
+communication device functionality when there is no data to be
+transmitted & received. The system on both the side of the link can
+disable some functionalities & save power during the period of low-link
+utilization. The MAC controls whether the system should enter or exit
+the LPI mode & communicate this to PHY.
+
+As soon as the interface is opened, the driver verifies if the EEE can
+be supported. This is done by looking at both the DMA HW capability
+register and the PHY devices MCD registers.
+To enter in Tx LPI mode the driver needs to have a software timer
+that enable and disable the LPI mode when there is nothing to be
+transmitted.

-/************************** EEPROM BANDS ****************************
- *
- * The iwl_eeprom_band definitions below provide the mapping from the
- * EEPROM contents to the specific channel number supported for each
- * band.
- *
- * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
- * definition below maps to physical channel 42 in the 5.2GHz spectrum.
- * The specific geography and calibration information for that channel
- * is contained in the eeprom map itself.
- *
- * During init, we copy the eeprom information and channel map
- * information into priv->channel_info_24/52 and priv->channel_map_24/52
- *
- * channel_map_24/52 provides the index in the channel_info array for a
- * given channel.  We have to have two separate maps as there is channel
- * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
- * band_2
- *
- * A value of 0xff stored in the channel_map indicates that the channel
- * is not supported by the hardware at all.
- *
- * A value of 0xfe in the channel_map indicates that the channel is not
- * valid for Tx with the current hardware.  This means that
- * while the system can tune and receive on a given channel, it may not
- * be able to associate or transmit any frames on that
- * channel.  There is no corresponding channel information for that
- * entry.
