Browse Source 
Arbitrary ethernet mask support is one step on the way to support for OpenFlow
1.1+. This patch set seeks to add this capability without breaking current
protocol support.

* 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. */
