/* Create a QinQ cloud filter
 *
 * The Fortville NIC has limited resources for tunnel filters,
 * so we can only reuse existing filters.
 *
 * In step 1 we define which Field Vector fields can be used for
 * filter types.
 * As we do not have the inner tag defined as a field,
 * we have to define it first, by reusing one of L1 entries.
 *
 * In step 2 we are replacing one of existing filter types with
 * a new one for QinQ.
 * As we reusing L1 and replacing L2, some of the default filter
 * types will disappear,which depends on L1 and L2 entries we reuse.
 *
 * Step 1: Create L1 filter of outer vlan (12b) + inner vlan (12b)
 *
 * 1.	Create L1 filter of outer vlan (12b) which will be in use
 *		later when we define the cloud filter.
 *	a.	Valid_flags.replace_cloud = 0
 *	b.	Old_filter = 10 (Stag_Inner_Vlan)
 *	c.	New_filter = 0x10
 *	d.	TR bit = 0xff (optional, not used here)
 *	e.	Buffer – 2 entries:
 *		i.	Byte 0 = 8 (outer vlan FV index).
 *			Byte 1 = 0 (rsv)
 *			Byte 2-3 = 0x0fff
 *		ii.	Byte 0 = 37 (inner vlan FV index).
 *			Byte 1 =0 (rsv)
 *			Byte 2-3 = 0x0fff
 *
 * Step 2:
 * 2.	Create cloud filter using two L1 filters entries: stag and
 *		new filter(outer vlan+ inner vlan)
 *	a.	Valid_flags.replace_cloud = 1
 *	b.	Old_filter = 1 (instead of outer IP)
 *	c.	New_filter = 0x10
 *	d.	Buffer – 2 entries:
 *		i.	Byte 0 = 0x80 | 7 (valid | Stag).
 *			Byte 1-3 = 0 (rsv)
 *		ii.	Byte 8 = 0x80 | 0x10 (valid | new l1 filter step1)
