  * Format: 48-bit Ethernet MAC address.

- * Masking: The nxm_mask patterns 01:00:00:00:00:00 and FE:FF:FF:FF:FF:FF must
- *   be supported for NXM_OF_ETH_DST_W (as well as the trivial patterns that
- *   are all-0-bits or all-1-bits).  Support for other patterns and for masking
- *   of NXM_OF_ETH_SRC is optional. */
+ * Masking: Fully maskable, in versions 1.8 and later. Earlier versions only
+ *   supported the following masks for NXM_OF_ETH_DST_W: 00:00:00:00:00:00,
+ *   fe:ff:ff:ff:ff:ff, 01:00:00:00:00:00, ff:ff:ff:ff:ff:ff. */
