- * H/W TCP & UDP Checksum Offloading
- * ---------------------------------
- * The chip supports both tx and rx offloading of UDP & TCP checksums, this
- * feature can be dynamically enabled/disabled. None have been implemented yet.
- * //TODO: update this when checksumming is implemented.
+ * REMAINING FEATURES
+ * ------------------
+ * There are a bunch of features that the chip supports but have not been implemented
+ * in this driver yet. This will serve as a TODO list for the author and other
+ * contributors to consider.
+ * 1. RX/TX checksum offloading: nothing has been implemented yet for TX checksumming,
+ * RX checksumming works with ICMP messages, but its broken for TCP/UDP packets.
+ * 2. Direct address translation filtering: implemented but not tested yet.
+ * 3. VLAN tag removal: not implemented yet.
+ * 4. Reading MAC address from the device tree: this is specific to Raspberry PI.
+ * 5. Support for USB interrupt endpoints.
+ * 6. Latency Tolerance Messaging (LTM) support.
+ * 7. TCP LSO support.
