 - **Statistics**
 
   - ``rx_good_bytes`` (ibytes) always includes VLAN header (4B) and CRC bytes (4B).
+    This behavior applies to 1300 and older series VIC adapters.
+    1400 series VICs do not count CRC bytes, and count VLAN header only when VLAN
+    stripping is disabled.
   - When the NIC drops a packet because the Rx queue has no free buffers,
     ``rx_good_bytes`` still increments by 4B if the packet is not VLAN tagged or
     VLAN stripping is disabled, or by 8B if the packet is VLAN tagged and stripping
     is enabled.
+    This behavior applies to 1300 and older series VIC adapters. 1400 series VICs
+    do not increment this byte counter when packets are dropped.
+
+- **RSS Hashing**
+
+  - Hardware enables and disables UDP and TCP RSS hashing together. The driver
+    cannot control UDP and TCP hashing individually.
